PROBLEM TO BE SOLVED: To provide an organic thin film transistor and its method for manufacturing which can manufacture by a simple wet process, excels in the transistor characteristics, and is excellent in time stability even in atmosphere or under high humidity. SOLUTION: The organic thin film transistor having a gate electrode, a gate insulation layer, an organic semiconductor layer, a source electrode, and a drain electrode is characterized in that the organic semiconductor material forming the organic semiconductor layer contains 0.05-1,000 ppm of a compound having a condensed ring which is a condensation of at least two or more rings of either aromatic hydrocarbon ring or aromatic heterocycles, or both in a part of the structure and halogens.
