An imaging apparatus includes: an optical system configured to collect incident light; an imaging element including a light receiver configured to receive light input from the optical system and perform photoelectric conversion to generate an electrical signal; and an optical system adhesive layer configured to bond the optical system to a principal surface of the imaging element where the light receiver is provided. The optical system adhesive layer is a photosensitive transparent adhesive for which patterning is performed through a photolithography process and which has a function of determining a position of the optical system relative to the light receiver.
