The metal cover 848 provides an effect of reducing electromagnetic interference in addition to providing a function of mounting the receptacle connector 800 to the circuit board 108. The metal housing 848 includes a top wall 8481 and a pair of bosses 846, the top wall 8481 is soldered above the mating portion 803 of the metal housing, and a pair of circuit board mounting legs 844 are bent downward from both ends of the top wall 8481 for inserting a circuit board. The top wall 8481 has an opening 8452 formed therein at a location corresponding to the resilient arm of the mating portion 803. The metal cover 848 is further provided with the above-described raised portion 846 at a rear edge corner thereof. The protrusion 846 has a first portion 8461 extending in a front-back direction, a second portion 8462 extending downward, and a bending piece 8463 bent inward from the second portion.
