Provided is a connector having a reduced profile that is capable of facilitating confirmation of the mounting on a circuit board and, simultaneously, demonstrating a satisfactory noise-shielding effect. A connector (10) according to the present disclosure includes: a first connector (20) equipped with a pair of outer peripheral walls (32) opposing each other and a fitting projection (33) formed between the pair of outer peripheral walls (32); and a second connector (70) equipped with a second insulator (80) having a fitting recess (83) fit to the fitting protruding (33) and a second shielding member (110) supported by the second insulator (80). When the first connector (20) and the second connector (70) are fitted to each other, the first shielding member (60) and the second shielding member (110) engage each other are partially spaced apart from the first insulator (30) and the second insulator (80), respectively.
