PURPOSE: To provide a key touch force detector of an electronic keyboard musical instrument which assures the easy and accurate conduction of a mounting operation with simple constitution, improves workability and facilitates key scaling. CONSTITUTION: This key touch detector includes plural elastic pieces 11a disposed in correspondence to respective keys 1 which are elastically deformed by the key touch force in a vertical direction and sensors 20 which detect the elastic deformation of the respective elastic pieces 11a. Comb-shaped elastic members 11 are formed by integrally connecting the root parts 11f of the plural elastic pieces 11a. |
