Claim 9:
10. A key structure comprising:
a key top having a swing center and configured to swing about the swing center when pressed by a user, the key top having a first bottom surface and a second bottom surface that are parallel to one another; and
a first elastic member and a second elastic member positioned adjacent to the key top in a first direction,
each of the first elastic member and the second elastic member including:
a base,
a pressed portion configured to be pressed by a corresponding one of the first bottom surface and the second bottom surface of the key top,
a skirt portion that connects the pressed portion to the base such that the pressed portion is spaced from the base, the skirt portion being elastically deformable when the pressed portion is pressed by the corresponding one of the first bottom surface and the second bottom surface of the key top, and
a pressing member positioned in a predetermined region on a side of the pressed portion the pressing member being surrounded by the skirt portion, and at least a first surface of the pressing member being conductive, wherein

a second direction is perpendicular to the first direction,
in a non-operated state of the key top, a distance in the second direction between a side of the predetermined region that is proximal to the swing center and a side of the first surface that is proximal to the swing center is longer than a distance in the second direction between a side of the predetermined region that is distal from the swing center and a side of the first surface that is distal from the swing center.
