PROBLEM TO BE SOLVED: To prevent the separation of a conductive portion inside a hole caused by repetitive screwing and unscrewing of a screw. SOLUTION: A conductive portion 12h for electrically connecting the bottom face 1b of a first housing 1 and a ground pattern 14f formed in a circuit board 14 is disposed in ditches 12g formed inside a hole portion 12d of a boss 12a. Because of this structure, even if a screw 13a is repetitively screwed in and out of the hole portion 12d, the screw 13a never rubs the conductive portion 12h, and hence the wear of the conductive portion 12h by being rubbed by the screw 13a is prevented.
