Imaging apparatus

An imaging apparatus comprising:

• an imaging element;
• a circuit board on which the imaging element is mounted, wherein the imaging element is mounted on a mounting surface of the circuit board;
• a holding metal plate having an opening for holding the circuit board;
• and
• a connector mounted on the circuit board and configured to transmit the signal acquired by the imaging element to another circuit,
• wherein the circuit board is in contact with and fixed to the holding metal plate on the mounting surface of the circuit board,
• wherein a linear expansion coefficient of the circuit board is smaller than a linear expansion coefficient of the holding metal plate,
• wherein one end surface of the imaging element parallel to a longer-side direction of the imaging element is directly fixed with a first adhesive to a respective opposing end surface of the holding metal plate that is parallel to the longer-side direction of the imaging element in the opening, and
• wherein another end surface of the imaging element parallel to the longer-side direction of the imaging element is directly fixed with a second adhesive to a respective opposing end surface of the holding metal plate that is parallel to the longer-side direction of the imaging element in the opening.
