Inspection device for image pickup apparatus

An inspection device for image pickup apparatus comprising:

• an angle-of-view conversion optical member made of a translucent member having a predetermined refractive index, the angle-of-view conversion optical member including a first surface and a second surface that is an opposite surface of the first surface, the first surface being configured to closely contact a surface of a distal end optical member constituting an optical system of the image pickup apparatus, the surface of the distal end optical member being exposed outside of an exterior body of the image pickup apparatus, wherein a thickness from the second surface to the first surface is set to a predetermined dimension;
• a test chart including a chart surface provided so as to closely contact the second surface of the angle-of-view conversion optical member, an image of the chart surface being picked up by the image pickup apparatus through the angle-of-view conversion optical member;
• and an illumination portion that illuminates the chart surface of the test chart, wherein the test chart is a reflection chart, and the chart surface of the reflection chart is irradiated with illumination light that is emitted from the illumination portion and enters the angle-of-view conversion optical member from a side surface located between the first surface and the second surface of the angle-of-view conversion optical member.
