In a mobile electronic equipment, a main body has a flat bottom surface and a flat side which cooperatively form a frame and having a recess with rib slots on its side. A camera unit is constructed by connecting a flexible cable to a substrate on which a camera IC portion is mounted. A holder has a window portion through which the camera IC portion is passed and a cover portion which covers the camera unit and which has ribs engaging with the respective rib slots. The camera unit is housed in the recess together with the holder in which the camera IC portion is passed through the window portion, and the ribs are fitted into the respective rib slots to incorporate the camera unit into the main body.
