A photoelectric connector includes a plug and a receptacle. The plug includes a plug housing 200, a first guide pin 220, a first signal transmitting/receiving member 230, a first electrode unit 260, and a plug housing biasing means 250. The receptacle includes a receptacle housing 300, a second signal transmitting/receiving member 330, a second electrode unit 360, and a second signal transmitting/receiving member biasing means 321. In a state in which the plug is fitted to the receptacle, the first electrode unit 260 and the second electrode unit 360 come into contact with each other and are electrically connected to each other; an opposite surface of the first signal transmitting/receiving member 230 and an opposite surface of the second signal transmitting/receiving member 330 come into contact with each other in a state in which the opposite surfaces are not movable relative to each other; the first and second signal transmitting/receiving members 230 and 330 are biased to a rear side of the plug by the second signal transmitting/receiving member biasing means 231; and the plug housing 200 is biased in a direction perpendicular to the axis line of the plug by the plug housing biasing means 250 and the second electrode unit 360.
