摘 要：

PROBLEM TO BE SOLVED: To enhance the manufacturing yield in an illuminance sensor.;SOLUTION: At a substrate front surface 21 side an illuminance sensor 1 is provided with an optical detection unit 3, having sensitivities to a visible light and a long-wavelength light; a signal processing circuit 4 which performs treatments of an amplification or the like, with respect to an optical detection signal generated in the optical detection unit 3 and outputs the optical detection signal; and a bonding pad 6 for outputting the optical detection signal from the signal processing circuit 4 to the outside. On a substrate rear face 15 side, the illuminance sensor 1 is provided with an optical filter 7 for

shielding the long-wavelength light. Since the optical filter 7 is provided at the substrate rear face 15 side, where

bonding pad 6 has not been allotted, wire bonding failure or the like due to
