To provide a good connector surely protecting a terminal connection part to which, a plurality of electric wires are connected.

The connector comprises a connector part 2 in which, a plurality of connection terminals 4, connected to an electric wire ends 5a of a plurality of electric wires 5, respectively, a cylindrical electric wire holding part 3 jointed to the rear end of the connector part 2, holding the nearing part of the plurality of electric wire ends 5a, a circular fixing member 8 into which, a plurality of electric wires 5 are inserted, and an elastic fixing member 6 into which, a plurality of electric wires 5 are inserted, located at the position getting closer to the electric wire ends 5a from the circular fixing member 8. Supporting rib protrusions 10, 11, 12, composing a peripheral direction groove 13 fixing the circular fixing member 8 to a prescribed position, and a peripheral direction groove 14 enabled to lock the elastic fixing member 6, are protrusively formed to the inner peripheral surface of respective parts 3a, 3b of an electric wire holding cylindrical part 3.
