CONSTITUTION: A laser navigation module(100) includes a printed circuit board(110), a laser irradiating unit(120), a light receiving unit, a lead unit, and a housing. The laser irradiating unit is mounted on the printed circuit board and irradiates laser light. Laser light is incident on a subject which is located on the housing through the lead unit. The housing covers the lead unit. The subject contacts an upper part(152).
