1. An optical connector comprising:
a ferrule having a fiber hole into which an optical fiber is inserted and a guide hole into which a guide pin is inserted;
a housing that accommodates the ferrule; and
a biasing member, disposed in the housing, that applies to the ferrule a biasing force directed toward a side close to an opening portion of the housing in an axial direction of the guide hole, the biasing force having nonlinear characteristics, wherein
the biasing member includes a first parallel spring having a first free length and a second parallel spring having a second free length smaller than the first free length, and
the first parallel spring and the second parallel spring are connected in parallel.
