Abstract
An apparatus includes a semiconductor layer including a conversion unit and a diffusion unit, and a plurality of wiring layers including a first wiring layer. The semiconductor layer includes a transfer transistor configured to send a signal based on a charge generated by the conversion unit to the diffusion unit, and an amplification transistor including a gate connected to the diffusion unit. The first wiring layer includes a control line configured to send a signal to drive the transfer transistor to a gate of the transfer transistor, a wire connecting the diffusion unit and the gate of the amplification transistor, and a first shield wire connected to a source or a drain of the amplification transistor and provided between the wire and the control line in a planar view.
