To easily remove electric wires with which an earth terminal is still connected.

When an elastic deflection part 11 is elastically deflected in such a way as to be parted from a holding member 30, a retaining projection (retaining member) 13 is dislocated from a retaining hole (retaining member) 35, as the retaining restriction of an earth terminal 10 is thereby released, the earth terminal 10 can thereby be taken out of a space between a body 20 and the holding member 30. Even if no troublesome removal operation is performed, since only simple operations in which an elastic deflection part 11 is elastically deflected, enable the electric wires W to be taken out of a body 20, the removal operation of the electric wires W can thereby be easily carried out.
