A handheld electronic device includes a casing, a camera unit, and a sealing unit. The casing confines an accommodating space, and is formed with a recess that is defined by a recess-defining wall. The recess-defining wall is formed with a hole that is in spatial communication with the recess and the accommodating space. The camera unit includes a camera housing and an electrical wire. The camera housing is disposed in the recess, and has a first end portion that is received rotatably in the hole in the recess-defining wall. The electrical wire has a first end portion that extends into the camera housing, and a second end portion that extends into the accommodating space. The sealing unit is disposed between and is in airtight contact with the recess-defining wall and the camera housing.
