摘要： With an aim of receiving a subject image at good sensitivity by improving the light collection efficiency of incident light, an image pick-up element includes a light-receiving portion, poly-silicon wiring formed on the light-receiving portion, and a potential well structure. The poly-silicon wiring is arranged so as to be overlapped with at least a part of the light-receiving portion, and is electrically connected to the light-receiving portion to perform the control of electric charges generated at the light-receiving portion, the switching of the light-receiving portion, and the like. The potential well structure is formed in at least a part of the area of the light-receiving portion in which the poly-silicon wiring is arranged, and the opened area of the potential well structure is sufficiently secured. The incident light entering the potential well structure is totally reflected by the inner wall of the potential well structure, and reaches the light-receiving portion or the poly-silicon wiring. The incident light reaching the poly-silicon wiring is transmitted through the poly-silicon wiring to be received by the light-receiving portion.

摘要： This invention has building members which include an image sensing portion, an optical member for forming a beam from an object to be sensed into an image on the image sensing portion, a positioning portion which positions the optical member, and a support member which holds the optical member and to which the positioning portion is fixed. When the optical member deforms along the optical axis upon a temperature change of the building members, the image sensing portion is deformed in the same direction as deformation of the optical member. The position of the image sensing portion is adjusted via a plurality of adjustment members movably attached to the support member. The image sensing portion is fixed to the support member after adjustment by adhering the image sensing portion and the adjustment members to each other, and adhering the adjustment members and the support member to each other.
