2. Description of the Related Art Generally, pumice cut into a shape suitable for use is known as a tool for removing the stratum corneum of the skin. However, for example, when removing the stratum corneum formed on the skin of the foot with pumice, the shavings that have been scraped get into the fine eyes of the pumice, so that the pumice causes clogging and the performance gradually deteriorates. . Further, the shavings that have once entered the inside of the pumice are difficult to take out, giving off a bad smell and causing a hygienic problem. To solve these problems,
Conventionally, for example, those described in JP-A-11-56668 or JP-A-7-8318 have been proposed. What is disclosed in JP-A-11-56668 is
A large number of nails are planted on a grip table and formed like a sword mountain. The stratum corneum is rubbed by the surface formed by the tips of the nails, and the stratum corneum is scraped off. The shavings left between the nails are removed with a brush or washed off with water.

Japanese Patent Application Laid-Open No. 7-8318 discloses a thin metal plate having flexibility, a large number of through-holes formed therein, and a beveling blade formed at a surface side edge of the through-hole.

Has become.

[0004]

Of the above-mentioned conventional removal tools, the former one of the sword-yama type is less likely to be clogged. However, when the swarf is collected at the center of the sword-yama and deeper from the nail tip, it is removed. There is a problem that it is difficult to maintain cleanliness. In addition, if the user accidentally slips off his / her hand during use, there is a danger of injury due to the shaved surface being formed by the needle tip, which poses a safety problem. In addition, in the latter case using a metal thin plate with a edging blade, when rubbing, the pressure is unstable from the aspect of strength and the usability is poor, and when the stratum corneum layer surface is pressed toward the thin plate side, the elasticity of the metal thin plate itself is reduced. Due to the deformation, the thin plate is deformed to the non-pressing portion side, and a sufficient contact pressure cannot be obtained, so that there is a problem that the removing operation takes time and is difficult to use. Furthermore, although precision manufacturing is possible because of manufacturing by electroforming, there is a problem that an increase in manufacturing cost is inevitable.
