Claim 0:
1. A skin stimulation brush, comprising:
a housing that forms a handle and a brush base provided to one end of the handle;
an electric circuit accommodated in the housing; and
a plurality of skin stimulation brush pins provided to the brush base in a protruding manner,
wherein each of the skin stimulation brush pins includes:
a base bottom member made of a metal, which is connected to the electric circuit so as to allow conduction of electricity from the electric circuit;
a body member being an elongated tubular body, which has a proximal end portion at which the base bottom member is disposed;
an electrode member, which is connected to an opening of the body member on a distal end side, and has a distal end being exposed, wherein the electrode member includes a shaft portion having an elongated shape, which extends from an intermediate portion to a proximal end of the electrode member, and the shaft portion of the electrode member is fitted into the distal-end opening portion of the body member; and
a metal shaft inserted into a tubular inner portion of the body member with an air gap, which is configured to couple the base bottom member and the electrode member while being in a compressed state in a length direction of the body member,

wherein the metal shaft has pliability that allows bending in a radial direction, and
wherein the body member has elasticity that allows bending in a radial direction.
