PROBLEM TO BE SOLVED: To provide a pressure sensor which is capable of preventing distortion or its influence from unnecessarily spreading to another sections even if there is a distortion generation factor in part of a sensor member or buffer member. SOLUTION: This pressure sensor for touch control of an electronic keyboard instrument has a buffer member 2 which receives pressing force from an operating section which extends in a key arraying direction and receives pressing force from an operating section which is a portion of the key or a portion of the member cooperating with the key at the time of key touch and a sensor member 1 which receives the pressing force past the buffer member and changes an output value according to the pressing force. In such a case, at least either of the buffer member 2 and the sensor member 1 is provided with notched parts apart spaces intervals in the key arraying direction. |
