ABSTRACT:
An image sensor100is provided with a first voltage maintainer61including two first voltage maintaining capacitors C1Va, C1Vbfor maintaining a voltage of signal input electrode47, and a second voltage maintainer62including a second voltage maintaining capacitor C2Vfor maintaining a voltage of bias voltage input electrode46. This image sensor100, even in a disconnected state from main body part200, is able to maintain the voltage of bias voltage input electrode46and the voltage of signal input electrode47during an image pickup operation and thus to implement image pickup.
