Camera module

An apparatus comprising:

• a camera module;
• and
• a case to which the camera module is mounted,
• the camera module comprising:
• a camera substrate that includes an image sensor;
• a base portion that is a case fixed to the camera substrate so as to surround the image sensor and includes a through hole passing through an opposing surface that opposes the camera substrate;
• a tube-shaped lens barrel portion that holds a lens therein and is disposed so as to communicate with the through hole on an outer wall surface side of the opposing surface;
• and
• an optical filter that is fixed to a fixing region formed on an inner wall surface of the opposing surface,
• the lens barrel portion including an air hole that communicates from a tip of the lens barrel portion to the through hole, through a tube-shaped wall of the lens barrel portion in a direction of an optical axis of the lens,
• the opposing surface including an air channel that communicates between and the through hole and a base inner space, the base inner space being a space surrounded by the base portion and the camera substrate,
• the air channel having a bent shape on a cross-section parallel to the optical axis.
