<;P>;PROBLEM TO BE SOLVED: To provide a grip pressure measuring method and measuring apparatus capable of detecting a deviation of a gripping position. <;P>;SOLUTION: The grip pressure measuring apparatus of the present invention includes a pressure sensor having first sensor parts 1g, 2g, and 3g and second sensor parts 1h, 2h, and 3h. This pressure sensor is capable of measuring a pressure by arranging the first sensor parts 1g, 2g, and 3g, and the second sensor parts 1h, 2h, and 3h, facing each other. In this measuring apparatus, the first sensor parts 1g, 2g, and 3g can be separated from the second sensor parts 1h, 2h, and 3h. At the time of measuring the pressure, the first sensor parts 1g, 2g, and 3g are fixed on the tool side, and the second sensor parts 1h, 2h, and 3h are fixed on the human body side. Preferably, a plurality of the first sensor parts 1g, 2g, and 3g are laid out. Preferably, a plurality of the second sensor parts 1h, 2h, and 3h are laid out. <;P>;COPYRIGHT: (C)2011,JPO&INPIT
