PROBLEM TO BE SOLVED: To relax a difference between portions relating to a detection sensitivity of a touch operation, while disposing a touch sensor along the main surface of a surface member.SOLUTION: An operation panel 1 includes: a surface member 5 having a first main surface 5a to be an object of a touch operation and a second main surface 5b on the reverse side of the first main surface; and a touch sensor 6 disposed along the second main surface 5b and detecting the touch operation for the first main surface 5a. The second main surface 5b is a quadratic surface bent to two or more directions including a horizontal direction (axial direction) only, while the first main surface 5b is a cubic surface bent to two or more directions including the horizontal direction (axial direction). Since the second main surface 5b of the surface member 5 is a quadratic surface, the touch sensor 6 can be disposed along this second main surface 5b. At the same time, since a difference between the thicknesses portions of the surface member 5 can be relaxed, the difference between the portions relating to the detection sensitivity of the touch operation can be relaxed. |
