Abstract: An endoscope includes an optical laminate and an image sensor. The optical laminate includes a first optical member that is a glass lens where an optical window is formed in a planar substrate, including a recessed portion or a protruding portion around the optical window, and a second optical member having a flat surface facing the substrate of the first optical member, and including a protrusion made of resin for being fitted with the recessed portion or the protruding portion. The flat surface of the second optical member is a surface of a glass substrate on the first optical member side. A resin lens of the second optical member is arranged on a surface on an opposite side of the flat surface. A flat portion excluding the optical window and the recessed portion or the protruding portion is in contact with the flat surface of the second optical member.
