Imaging apparatus

An imaging apparatus comprising:

• an optical lens having an optical axis in a first axial direction;
• an imaging element facing the optical lens in the first axial direction;
• an illumination adjustment unit having an illumination adjustment part adjusting a luminous flux incident on the imaging element from the optical lens, with the illumination adjustment part being arranged on the optical axis by being inserted between the optical lens and the imaging element in a second axial direction orthogonal to the first axial direction;
• and
• a supporting member having a first supporting part supporting the optical lens, a second supporting part supporting the imaging element, and a coupling part coupling the first supporting part and the second supporting part to each other, the supporting member being configured to form a space, into which the illumination adjustment unit is inserted in a third axial direction orthogonal to the first axial direction and the second axial direction, with the space being formed by the first supporting part, the second supporting part, and the coupling part.
