Patent Number: 8,717,486

Title: Imaging unit and imaging device

Abstract: A technique of enabling both of higher functionality and higher accuracy in a compact optical system is provided. To achieve this object, an imaging unit has a laminated structure formed by laminating a plurality of layers including: an image capturing element layer including an image capturing element part; a lens layer capable of changing a distance from the image capturing element layer; and an actuator layer including a movable part for moving the lens layer; and a signal transmitter disposed so as to connect the actuator layer and the image capturing element layer, and transmitting a drive signal for driving the movable part from the image capturing element layer side to the actuator layer, and the movable part is deformed according to the drive signal transmitted through the signal transmitter, and the actuator layer is provided between the image capturing element layer and the lens layer.
