PROBLEM TO BE SOLVED: To provide a diode in which a quantity of light is measured stably without being influenced by disturbance. SOLUTION: A gate electrode 114 is provided on the i-region 112 of a diode 100 through an insulating film, and an n-region 117 is provided between the i-region 112 and the n-region 113. The gate electrode has a bent planar shape and a reverse bias is applied between pn. COPYRIGHT: (C)2005,JPO&NCIPI
