Provided herein is a skin resistance measuring device having a simple structure and capable of accurately measuring a skin resistance. An AC voltage generated by a high-frequency power source (21) is applied to a first electrode (11). A detection circuit (30) detects a current of a second electrode (12). An inductive element (25) is provided, for example, in an electric path extending from the high-frequency power source (21) to the first electrode (11). A controller (40) changes and controls a frequency of the high-frequency power source (21), receives a detection signal (S1) from the detection circuit (30), and calculates an impedance of the human body which has touched an electrode section (10). The skin resistance of the human body is calculated based on a value of impedance at a frequency where the impedance is a minimum.
