A lance which protrudes from the outside surface of a terminal body to prevent falling out of a cavity of a connector housing includes a lance body of an inclined plate shape whose protruding length from the outer surface of the terminal body towards the outside gradually increases from the front end side of the terminal body to the back end side, and a shielding plate which extends from the back end edge of the lance body towards the outer surface of the terminal body so that an opening which opens towards a terminal back end is not formed between the back end edge of the lance body and the outer surface.
