PROBLEM TO BE SOLVED: To provide a pressure sensor for touch control for an electronic key board music instrument having a structure coming into contact with a damper member and realizing a precise touch control. SOLUTION: A pressure sensor is provided with a damper member 3 coming into contact with an operation part with a damper action during key touching time, and a sensor body 1 laminated on the damper member 3. Intermittent partial adhesion is performed in a key arranging direction between contact faces of the damper member 3 and the sensor body 1. This partial adhesion is performed as an adhesion at a position required for an adhesion strength in a middle area of contact positions on the damper members 3 of the neighboring operation parts. Or a gap forming member is provided such that the gap forming member forms a gap relative to a member for pressing positioned on one side of the both sides of the sensor body 1 in a pressing direction during non-pressing time. |
