PROBLEM TO BE SOLVED: To provide a contact type linear sensor capable of reducing power consumption. SOLUTION: A source follower circuit included in a solid-state imaging element in the contact type linear sensor has a depletion MOS transistor connected to a power supply potential and an enhancement MOS transistor connected to a ground potential, wherein a signal voltage passed through an amplifier circuit is applied to the gate electrode of the depletion MOS transistor and a selection signal is applied as a gate voltage of the depletion MOS transistor.
