PROBLEM TO BE SOLVED: To provide a pressure sensor for touch control of the electronic keyboard musical instrument which stably operates by optimizing the state of contact between a side end part of a sensor member and the internal surface of the side wall of a case. SOLUTION: The pressure sensor 1 is equipped with a sensor member 13 which generates a sensor output corresponding to a pressing force when receiving the pressing force from a part associated with a key by key depression and the case 14 which contains the sensor member. In this case, the sensor member 13 and case 14 are so formed that contact places between the side end part of the sensor member 13 and the side wall internal surface of the case 14 are scattered at intervals. |
