PURPOSE:To provide a highly sensitive photosensor excellent in response to light. CONSTITUTION:A condensed polycyclic aromatic compound film where the number of condensed benzene rings is not less than four and not more than thirteen is made on a semiconductor substrate. A photosensor detects the light from the change of the electric property accompanying the light application of this sensor, by forming the film of a condensed poIycyclic aromatic compound on the semiconductor substrate. The photosensor is highly sensitive, and is excellent in response to light. Furthermore, since the manufacture of the sensor can be performed with a low-temperature substrate, and it is excellent in surface property of the film and the smoothness, it is useful in industry.
