An electronic device of the present application includes case 1, leg 3 that has a hollow stem portion, and leg fixing part 4. Leg fixing part 4 is a part that is formed in one face of case 1 and that has a hole into which leg 3 is inserted and that includes case thread ridge portion 4a formed on an inside face of the hole. Leg 3 has first screw structure portion 3a and second screw structure portion 3b formed on a circumferential face of the stem portion thereof, first screw structure portion 3a is formed of a plurality of turns of continuous thread ridge that can be screwed into case thread ridge portion 4a, second screw structure portion 3b is formed of one or more turns of thread ridge at the same screw pitch as first screw structure portion 3a and screwed into case thread ridge portion 4a before first screw structure portion 3a is screwed when leg 3 is inserted into the hole. Case thread ridge portion 4a is divided into separate thread ridge portions. Second screw structure portion 3b includes a coupling portion 5 that can be displaced to a central side of the stem portion of leg 3, guide portion 5a, and an idle turn inducing portion 5b. Guide portion 5a guides case thread ridge portion 4a to second screw structure portion 3b when leg 3 is inserted into the hole while it is turned in a direction in which leg 3 is inserted into case 1. Idle turn inducing portion 5b idly turns second screw structure portion 3b with respect to case thread ridge portion 4a when leg 3 is turned in a direction in which leg 3 is pulled out of case 1.
