Patent ID: 8792044

Claim:
A method for manufacturing an image pickup device, the method comprising the steps of: manufacturing an optical unit which comprises, in order from an object side: a first lens block including a first glass substrate on an object side surface of which a first lens part and a first non-lens part surrounding the first lens part and extending to a circumference of the first glass substrate are formed of resin, and an image side surface of which a second lens part and a second non-lens part surrounding the second lens part are formed of resin; and a second lens block including a second glass substrate on an object side surface of which a third lens part and a third non-lens part surrounding the third lens part are formed of resin, and on an image side surface of which a fourth lens part and a fourth non-lens part surrounding the fourth lens part and extending to a circumference of the second glass substrate are formed of resin, wherein the second non-lens part and the third non-lens part are directly bonded to face each other, and wherein the first non-lens part and the fourth non-lens part are thinnest at the circumference of the first glass substrate and the circumference of the second glass substrate, respectively; bonding a glass spacer, which has an opening at a position corresponding to the first lens part through the fourth lens part, such that one end surface of the glass spacer is directly bonded to the surface on which the fourth lens part is formed; bonding a sensor unit, which has a glass cover member and an image sensor provided a predetermined distance away from the cover member, to the other end surface of the spacer, wherein at least a side surface of the first lens block, a side surface of the second lens block, and a side surface of the spacer are formed on the same plane; and mounting a lens cover such that the lens cover covers the side surfaces.
