To provide a surface mounting clip having holding springs paired in an opposition state to hold a plate material inserted therebetween with elastic repulsion force, wherein electric contact with the plate material inserted between the holding springs is stabilized.

The peripheral wall W of a shield case C is inserted between the paired holding springs 12L, 12R. The lower end of the peripheral wall W is pressed against a bottom spring 17 to be elastically deformed downward. When a hole H is locked by a projection 15e, the hole stops with a click. Thus, the hole H is locked by the projection 15e and the elastic repulsion force of the bottom spring 17 acts as a force for pushing up the peripheral wall W, so a holding force to the shield case C and electric conduction become extremely excellent. The bottom spring 17 and the lower end of the peripheral wall W of the shield case C are prevented from being separated when vibration is applied.
