Abstract

An artificial nail ( 1 ) has a member made of a material having electrical conductivity. The artificial nail ( 1 ) is given electrical conductivity by mixing an electrically conductive material into plastic serving as a base material. As the electrically conductive material, a carbon-based material, such as carbon black, carbon fiber, or black lead, or a metal-based material, such as a fine metal powder, a metal oxide, metal fiber, or a whisker, is used. Alternatively, the base material for the artificial nail ( 1 ) per se is an electrically conductive resin.

Claims (14)

1. An artificial nail mountable on a human nail for operating capacitive touch panels, comprising:

a hard base member forming a majority of the artificial nail, said hard base member having a lower mounting side opposite an upper principal side and a proximal cuticle end opposite a distal joining portion;

an elastic tip member forming a distal tip portion of the artificial nail, said elastic tip member having a lower mounting side opposite an upper principal side and a distal end opposite a proximal joining portion,

said elastic tip member and said hard base member being joined to each other at a joining surface formed by overlapping and adhering said respective joining portions such that the mounting sides form a continuous mounting surface of said artificial nail and the principal sides form a continuous principal surface of said artificial nail, and

said joining surface has a proximal end at said mounting surface and a distal end at said principal surface such that said joining surface is at an oblique angle to said principal surface of said artificial nail,

wherein the elastic tip member and the hard base member are made from

an electrically conductive material mixed with a base material, and an amount of the electrically conductive material is a value which provides said artificial nail with an electrical conductivity that is equal to and not greater than an electrical conductivity of a human body.

2. The artificial nail as set forth in claim 1 , wherein the electrically conductive material is a carbon-based material, a metal-based material, or an electrically conductive resin.

3. An artificial nail mountable on a human nail for operating capacitive touch panels, comprising:

a hard base member forming a majority of the artificial nail, said hard base member having a lower mounting side opposite an upper principal side and a proximal cuticle end opposite a distal joining portion;

an elastic tip member forming a distal tip portion of the artificial nail, said elastic tip member having a lower mounting side opposite an upper principal side and a distal end opposite a proximal joining portion;

said elastic tip member and said hard base member being joined to each other at a joining surface formed by overlapping and adhering the respective joining portions such that said mounting sides form a continuous mounting surface of said artificial nail and said principal sides form a continuous principal surface of said artificial nail, and

said joining surface has a proximal end at the mounting surface and a distal end at the principal surface such that said joining surface is at an oblique angle to the principal surface of the artificial nail,

wherein the elastic tip member and the hard base member are made from electrically conductive material providing said artificial nail with an electrical conductivity that is equal to and not greater than an electrical conductivity of a human body.
