Claims

[Claims for Utility Model Registration] (1) A rod-shaped measuring device whose tip is pressed against the skin surface to measure skin moisture, and a main body connected to the measuring device, On the tip surface,
Two conductor regions are provided that form a DC circuit only when the skin is pressed and serve as a positive electrode and a negative electrode, and an extraction means is provided for extracting the electrical resistance of the DC circuit when the skin is pressed as an electrical signal, and is provided in the main body. In this method, an arithmetic processing circuit that receives an electrical signal outputted from the extraction means to calculate the skin moisture content, and a display means that displays the skin moisture content based on the processed signal outputted from the arithmetic processing circuit are provided. Characteristic skin moisture measurement device. (2) Claim (1) wherein one of the two conductor regions is arranged in a circular shape at the center of the sensing surface, and the other is arranged in an annular shape at the edge of the sensing surface so as to surround the circular conductor region. ) The skin moisture content measuring device described in ).
