A keyboard includes a plurality of keys and an illumination module. Each key includes a membrane switch structure, a scissors-type supporting member, a light-storing and light-adjusting elastic member, and a keycap. The light-storing and light-adjusting elastic member is accommodated within a receptacle of the scissors-type supporting member. The scissors-type supporting member contains a light-storing material. The light-storing material has a property of storing the radiant energy of the light from the light source and gradually emits visible ray in the dark. After the external light source is turned off, the radiant energy stored in the light-storing material could emit the visible ray for an afterglow time.
