PROBLEM TO BE SOLVED: To provide an organic transistor which has high mobility of carries and whose threshold voltage and operating voltage are suppressed low. SOLUTION: The organic transistor has a gate electrode formed on a substrate, a gate insulating film formed on the gate electrode, an organic semiconductor film formed on the gate insulating film, and a 1st electrode and a 2nd electrode which are connected to the organic semiconductor film, the organic transistor being characterized in that the gate insulating film includes a 1st gate insulating film and a 2nd gate insulating film contacting the gate electrode and the 1st gate insulating film has a higher specific dielectric constant than the 2nd gate insulating film, which has a larger angle of contact with pure water than the 1st gate insulating film.
