Abstract: An electrical connector for a circuit board is attached to one circuit board and fits to a mating connector mounted on another circuit board, so that the two circuit boards are electrically connected via a group of terminals. In the electrical connector, a housing includes an outer circumferential surface comprised of a pair of sidewall surfaces and a pair of end wall surfaces. In the electrical connector, a shielding plate is attached to the housing for covering the outer circumferential surface of the housing. The shielding plate comprises two shielding members that extend in a circumferential direction. One of the shielding members covers a part of the outer circumference of the housing, and the other shielding member covers the remaining portion. Each shielding member includes a side portion for covering one of the sidewall surfaces and an end portion for covering at least a part of the end wall surfaces.
