Gosho Aoyama derived Shinichi Kudo's Alias "Conan Edogawa" from Sir Arthur Conan Doyle, Author of the Famous Sherlock Holmes Stories, and Edogawa Ranpo, the Pen Name of the Japanese Fictional Mystery Writer Hirai Tarō.
Hirai Tarō himself got the Pen Name "Ranpo Edogawa" from a Transliteration of "Edgar Allan Poe".
Hirai Tarō realized that pronouncing Edgar Allan Poe's Full Name in a Japanese Accent sounds like "Edogawa Rampo".
Gosho Aoyama himself stated that Conan Edogawa's Hair Style was designed in about one minute.
While creating Conan Edogawa's Hair Style, Gosho smoothed Yaiba's Hair from Yaiba and added a Tuft on the back of his head modeled after the Apostrophe Hairstyle of Kabu from Sally the Witch.
Conan's Tuft on top of his head comes from the Fictional Character Shichimi from Niji Iro Tōgarashi.
Conan Edogawa's use of Glasses as a Disguise was modeled after Clark Kent from Superman.
Conan Edogawa's Clothes were modeled after Shichi-Go-San (7-5-3) Clothing, which were the clothes Gosho Aoyama used to wear such as bow tie and shorts when he was young.
Conan Edogawa often uses the Expression "Ah-Le-Le?" when he is trying to point out a clue, something that is usually said by Japanese Grade Schoolers.
The "Ah-Le-Le?" Expression was once said by Kogoro Mouri out of irritation to Conan and by Ai Haibara who tries to imitate Conan's childish expression.
Conan's Habit of acting juvenile to disguise his real abilities by expressing "Ah-Le-Le?" also draws the ire of the Detective Boys.
Conan Edogawa's Bad Singing came to light as a joke after the anime began airing because Conan's Voice Actress, Minami Takayama, is a well-known Singer.
In Episodes 81-82, Minami Takayama herself was kidnapped and Conan, who sounds similar to her, tries to take her place at the concert. However, despite having similar voices, they sound completely different when it comes to singing.
Conan Edogawa owns two Cellphones, the one that he uses as Conan Edogawa and the one that he uses as Shinichi Kudo.
Conan is also shown using different kinds of Cellphones that vary from time to time throughout the Detective Conan series.
Conan Edogawa seems to have Plane Narcolepsy which also shows up when he is Shinichi Kudo as well.
Conan Edogawa appears to be a Big Fan of Haginyan, a Cat Mascot, which was shown in Episode 891.
Conan Edogawa/Shinchi Kudo's Favorite Food is Lemon Pie and Favorite Drink is Iced Coffee, which were first shown in Episodes 100-101 and in Movie 18.5, respectively.
Conan Edogawa/Shinichi Kudo and Ran Mouri share the same Blood Type, although their Blood Type still remain unknown.
