Patent ID: 8907266

Claim:
A light-receiving device array comprising: a photodiode array, being provided with a plurality of light-receiving sections on a semiconductor substrate, each of the light-receiving sections comprising a first conductivity type electrode and a second conductivity type electrode and converting an input optical signal into an electric signal; and a carrier, having a front surface on which the photodiode array is disposed so as to be connected thereto, and a rear surface located on an opposite side to the front surface, the carrier comprising: a plurality of pair of electric lines, each of the pair of electric lines being formed from a first electric line connected to the first conductivity type electrode of the corresponding light-receiving section and being formed on a part of the front surface, and a second electric line connected to the second conductivity type electrode of the corresponding light-receiving section and being formed on a part of the front surface adjacent to the first electric line; a first ground electrode being formed on a part of the front surface and extending between one pair of electric lines of the plurality of pair of electric lines and a pair of electric lines adjacent to the one pair of electric lines; and a second ground electrode being formed on at least a part of the rear surface and being electrically connected to the first ground electrode.
