Abstract:
1. An image pickup device mounted on a base board, comprising: an image pickup element including a plate mounted on a top surface of the base board, the plate having a thickness, a photoelectrically converting section provided on a top surface of the plate and having pickup elements, a peripheral top surface formed on the top surface of the plate around the photoelectrically converting section and a side surface of the plate adjoining the peripheral top surface; an optical member including a lens section to form an image of an object on the photoelectrically converting section of the plate, a leg section to support the lens section and a contact surface provided at a lower end of the leg section, the contact surface resting on only the peripheral top surface of the plate such that the lower end of the leg section does not extend beyond the top surface of the plate; and a lens frame having a slidable contact surface at a lower end thereof and an inner space in which the optical member is accommodated so as to come in contact with an inner wall of the lens frame; wherein the optical member is mounted on the image pickup element such that a first position between the lens section and the photoelectrically converting section of the image pickup element in an optical axis direction is determined by resting the contact surface of the optical member on only the peripheral top surface or with a top surface member when the top surface member is provided on the peripheral surface, and wherein the lens frame is mounted on the base board such that a second position between the lens section and the photoelectrically converting section of the image pickup element in a direction perpendicular to the optical axis is determined by bringing the slidable contact surface of the lens frame in direct contact with only the top surface of the base board and by positioning the slidable contact surface of the lens frame on the base board.
