Aconnector (1) according to the present invention includes a housing (2) defining an insertion section (5) into which a male connector (100) is inserted from the outside and a flow path (6) communicating with the insertion section (5) and an elastic valve body (3) which has a slit (11) and blocks the insertion section (5). An inner wall defining the flow path (6) is integrally formed with a liquid collision face (39) which faces a tip opening (104) of the male connector (100) inserted in the insertion section (5) in an insertion direction (B) of the male connector (100) and collides with liquid flowing out from the tip opening (104).
