Summary:PROBLEM TO BE SOLVED: To provide a coordinate position inputting device with satisfactory feel and excellent operability, and with the high degree of freedom of design in which any size, control stroke, or operational force is not limited without using any spacer for electrical insulation. SOLUTION: This device is composed of a surface sheet 1 having flexibility, case 2 for holding the surface sheet 1, liquid sealed object 3 sealed between the surface sheet 1 and the bottom face of the case 2, more than two pressure sensors 4A and 4B fixed to the bottom face of the case 2, and coordinate position operating means 5 to which the signals of the pressure sensors 4A and 4B are inputted for calculating a coordinate position to which an object such as a finger is brought into contact. Thus, a coordinate position inputting device with satisfactory feel due to the softness of the sealed object 3 and with excellent operability can be realized.
