PROBLEM TO BE SOLVED: To provide an electronic device having a switch structure like this in which there is no thickness restriction and a uniform operation feeling on each of push-down portions can be obtained even if there are provided a plurality of push-down portions. SOLUTION: In the electronic device, slits are formed on a first external member and a region surrounded by slits is used as a push-down portion of the switch. While a groove portion is formed near a region through which both ends of the slit of the first external member are connected, at least one out of number, width and depth of the slits increases as the distance from the circumference of the first external member to the push-down portion becomes longer.
