An image pickup apparatus includes an image sensor, a first circuit board on which the image sensor is mounted, a second circuit board facing the first circuit board, a flexible board that electrically connects the first circuit board and the second circuit board, and a fan. The image sensor moves within a movable range of the image sensor in a direction different from an optical axis direction. The flexible board includes a bent portion that is located closest to a side of the flexible board connected to the first circuit board. The flexible board is bent in an area overlapping the movable range of the image sensor in the optical axis direction. As viewed from the optical axis direction, an inner surface of the bent portion is disposed to be outside a range of a blowing direction of an airflow discharged from a vent of the fan.
