Patent ID: 8174087

Claim:
An electromagnetic wave detecting element comprising: a plurality of sensor portions, each of the sensor portions having: a semiconductor layer provided in correspondence with intersecting portions of one of a plurality of scan lines and one of a plurality of signal lines that are disposed so as to intersect one another, the semiconductor layer generating charges by being irradiated by electromagnetic waves expressing an image that is an object of detection, a first electrode formed by an electrically-conductive member that has transmittance with respect to the electromagnetic waves, at an irradiation surface side of the semiconductor layer to which the electromagnetic waves are irradiated, the first electrode applying bias voltage to the semiconductor layer, and a second electrode formed at a non-irradiation surface side of the semiconductor layer with respect to the electromagnetic waves, the second electrode collecting the charges that are generated at the semiconductor layer; and a common electrode line formed at an electromagnetic wave downstream side of the sensor portions, and connected to each of the first electrodes via respective contact holes, and supplying the bias voltage; a first insulating film provided between the plurality of sensor portions and the common electrode line and insulating the plurality of sensor portions and the common electrode line, the respective contact holes being formed in the first insulating film; and a plurality of contacts whose respective one ends are connected to the first electrodes via the contact holes respectively, and whose other ends are connected to the common electrode line.
