PROBLEM TO BE SOLVED: To provide a tactile sense switch device in which the arrangement and form of a switch are easily visible in a simple structure and a switch surface can be imparted with an illumination effect. SOLUTION: ThE device is composed of an elastic sheet 10 having permeability, a light source portion 20 and a tactile sense switch portion 30. The tactile sense switch device having the illumination effect is achieved by driving a piezoelectric element 32 of the tactile sense switch portion 30 to transform an elastic sheet 10 and by irradiating the inside of the elastic sheet 10 from the light source portion 20 with light.
