A connector for an electric vehicle in which a bus bar connecting portion of a terminal is secured and connected, in parallel, to a plate-like bus bar arranged in either a vertical or horizontal orientation. In the connector, a connector housing has a terminal accommodating chamber in the form of a substantially cylindrical space, and a rotation-preventing face is provided on the inner wall of the terminal accommodating chamber to radially and inwardly protrude from the inner wall. A body portion of the terminal is formed into a rod to be fitted into the terminal accommodating chamber. The bus bar connecting portion in the form of a plate, with a width equal to an outer diameter of the body portion, is extended from the rear end of the body portion. Two slants are formed on the body portion by partially removing the body portion along two planes intersecting perpendicularly to each other. The slants selectively abut against the rotation-preventing face when the terminal is inserted into the terminal accommodating chamber.
