ABSTRACT:
Disclosed are a key sheet for a pointing device and a pointing device using a magnet compact in terms of both magnetic force and size to allow a reduction in thickness. Between a pusher (14f) opposed to a contact input portion (E) of a board (P) and a magnet (11) fixed to a base sheet (14) at an outside position around the pusher (14f) as a center so as to be away from a key top (15), there is provided an elastic flexible portion (14d) allowing displacement in a depressing direction through depression of the key top (15) toward the contact input portion (E). As a result, it is possible to perform depressing operation on the key top (15), with the magnet (11) being provided on the base sheet (14), making it possible to perform switch input, such as confirmation input.
