ABSTRACT:
In a photodiode array1,incident-side depressions7formed by thinning from the incident surface side of light to be detected are arranged in an array, whereas opposite-side depressions11formed by thinning regions corresponding to regions formed with the incident-side depressions7from the side opposite from the incident surface are arranged in an array. The bottom of the opposite-side depressions11is formed with a pn junction3,whereby photodiodes of pn junction type are arranged in an array.
