A skin stimulation brush pin includes an elongated tubular body, a base bottom member, an electrode member, and a metal shaft. The elongated tubular body has a proximal end portion. The tubular body includes a radially contracted portion on a distal end side of the tubular body. The base bottom member is made of a metal to allow conduction of electricity from an electric circuit. The base bottom member is at the proximal end portion of the elongated tubular body. The electrode member is connected to an opening of the tubular body on the distal end side thereof and has an exposed distal end, the radially contracted portion of the tubular body radially protruding toward the electrode member. The metal shaft is in a tubular inner portion of the tubular body to couple the base bottom member and the electrode member.

Skin stimulation brush

A skin stimulation brush includes stimulation brush pins, each including a base bottom member made of a metal, which is connected to an 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 connected to an opening of the body member on a distal end side, and having a distal end being exposed; 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. The metal shaft has pliability that allows bending in a radial direction. The body member has elasticity that allows bending in a radial direction.
