Imaging apparatus and photoelectric conversion element package retaining unit

An imaging apparatus comprising:

• a photographic lens barrel unit including a photographic lens optical system;
• a photoelectric conversion element package including electrodes formed on a rear surface of a light-receiving surface;
• a printed circuit board electrically connected to the electrodes of the photoelectric conversion element package, wherein a first opening is formed in an area corresponding to an inside of the electrodes of the photoelectric conversion element package in the printed circuit board;
• and
• a retaining member configured to retain the photoelectric conversion element package so that the light-receiving surface of the photoelectric conversion element package is arranged perpendicular to an optical axis of the photographic lens optical system, wherein the retaining member includes:
• a positioning unit configured to position the photoelectric conversion element package in an axial direction orthogonal to the light-receiving surface by abutting on the photoelectric conversion element package outside the electrodes of the photoelectric conversion element package;
• and
• a second opening formed to pour an adhesive into the area corresponding to the inside of the electrodes of the photoelectric conversion element package.
