PROBLEM TO BE SOLVED: To provide a film fixing structure that enables transparency of an electrode film used for an electrostatic capacity type switch device to easily adhere to a panel at low cost, and suppress the detection sensitivity of a touch operation from varying between sites.SOLUTION: A switch device 1 has an overlay 2 (panel) having a switch part 24 which is subjected to a touch operation by a user. A transparent electrode film 3 having an electrode part 31 for detecting the touch operation to the switch part 24 is disposed at the back surface side of the overlay 2. The electrode film 3 is fixed to the back surface 22 of the overlay 2 by a general-purpose double-sided tape 4 at the outer peripheral portion of the electrode film 3. A groove is formed at a portion of the back surface 22 where the general-purpose double-side tape 4 is disposed, and an air layer between the overlay 2 and the electrode film 3 is thinned by the groove. No adhesive agent exists in an area (transparency-indispensable area) of the electrode film 3 where the electrode portion 31 is formed.SELECTED DRAWING: Figure 1 |
