Abstract
A portable electronic device includes a casing provided with a display on its front face and having ends gripped by both hands of a user, and at least one LR-button provided on a side face of the casing. The LR-button includes: an elongated button body having seizing members on both ends, the seizing members contacting against an inner side of the casing to prevent the button body from being detached from the casing; a deformation member pressed by a back of the button body when the button body is pressed; and switch contacts electrically conducted due to the deformation of the deformation member. When one end of the button body is pressed, the button body pivots about a contact point where said seizing means provided on the other end of the button body comes into contact with the casing.
