Key switches and an electronic device are provided, which have excellent design in which the key tops cover at least the whole of the width direction and the sides. A key switch (100) has a flat key top (110) in which adjacent key are disposed with no space therebetween, and portions of the key top (110) corresponding to keys located at the left and right ends of the key switch (100) each has a curved surface R as an end part (100a) of the key switch (100), which wraps around a side of a case and fits into a groove part (220a) of an outer frame (220). The key switch (100) includes the key top (110), a metal frame (120), and an elastic plate member supporting substrate (130), and a backside of the key top (110) is bonded to surfaces of elastic plate members (132, 133) of the elastic plate member supporting substrate (130) by silicon adhesive. The metal frame (120) is sandwiched between the key top (110) and the elastic plate member supporting substrate (130). |
