However, in the prior art, the bristle 6a, which corresponds to the bristles of the brush, is formed of a single material, but the tip of the bristles is preferably made of a hard material in order to give a massage effect to the portion in contact with the skin. When the brush was pressed against the skin, it was preferable that the body of the hair was softer than the tip and had moderate flexibility in order to relieve excessive pressing pressure.

Therefore, as a means for solving the above-mentioned problems, the skin stimulation brush pin according to the present invention has an elongated body member made of a conductive resin that can be conductively connected to the electric circuit from the electric circuit, and a tip of the body member. It is characterized by having a metal electrode member that is exposed and attached to a portion, and a conductive adhesive that is filled between the tip surface of the body member and the electrode member.

The tip of the body member is formed with a convex portion whose diameter is reduced inward in the radial direction from the peripheral surface of the central portion of the body member via a step, and the inside of the electrode member is formed in a dome shape. It is also preferable that the convex portion is fitted in the concave portion. The convex portion formed at the tip of the body member is fitted into the inner concave portion of the electrode member, and then a conductive adhesive is filled between the convex portion and the electrode member to form a conductive resin.

Further, it is preferable that the lower end of the electrode member is in contact with the step. As a result, the current can be directly conducted from the body member made of the conductive resin to the electrode member through the step, and all the current conducted from the body member to the electrode member is passed through the conductive adhesive. This is because the conductive efficiency can be increased more than that.

Further, the electrode member is preferably made of silver. This is because silver is a highly conductive metal having an appropriate softness, and since the electrode member is made of silver, it feels good to the touch when the pin is brought into contact with the skin. On the other hand, in addition to silver, copper, gold, or platinum can be used because it has excellent conductivity as an electrode member. Further, as the electrode, stainless steel, aluminum or the like can also be used.

Further, it is also preferable to have a primer layer between the conductive adhesive and the electrode member. Since the primer layer is present between the conductive adhesive and the electrode member, it is possible to reduce the possibility that the electrode member is detached from the conductive adhesive.

Furthermore, it is preferable that the body member has elasticity that allows it to bend in the radial direction.

Further, it is preferable that the body member is made of conductive silicone rubber.

Further, the skin irritation brush according to the present invention is a skin irritation brush in which a plurality of pins for the skin irritation brush are projected on a brush stand, and the handle and the brush stand provided at one end of the handle are provided. A housing is provided, and the electric circuit is housed in the housing.

Further, it is preferable that the electric circuit used in the skin irritation brush is configured so that a low frequency current can be applied to the body member.

According to the present invention, the electric current conducted from the electric circuit through the body member made of the conductive resin can be transmitted to the entire inner side surface of the electrode member via the conductive adhesive, so that the electrode member and the body member can be transmitted. It is possible to maintain the adhesive force with the skin and maintain the service life of the skin stimulating brush pin that is repeatedly pressed against the skin for a long period of time.
