A camera module with internal structural elements housed inside a housing space formed by joining two cases together achieves a sufficient joint strength between both cases even though the thickness of the case walls is reduced to make the outer shape smaller, as well as a size reduction of the camera module is enabled, when the two cases are joined together by ultrasonic welding. The joint surfaces where the two cases are joined together are inclined relative to a plane orthogonal to the optical axis direction of a lens unit housed inside the camera module. Thereby, the area of joint surfaces is increased as compared with the case where the joint surfaces are parallel to the plane orthogonal. Also, since interference between a horn for applying ultrasonic waves during ultrasonic welding and the external connection part is avoided, the camera module can be made smaller. |

1. A camera module comprising: a first case and a second case both made from a synthetic resin, the first case and the second case being joined together in a water tight manner to form a housing part,
the housing part including a lens unit having an objective lens at a top thereof, an imaging element, and a printed wiring board, which are accommodated therein, the first case having an upper face in which an opening is formed for exposing the objective lens, wherein joint surfaces of the first case and the second case where both are joined together are inclined relative to a plane orthogonal to an optical axis direction of the lens unit. |
