PROBLEM TO BE SOLVED: To provide a multidirectional key structure which can prevent incorrect operations by enabling to press down to any operation direction with almost same load even when a protruding part in order to hook a key top member of a multidirectional key on the inner wall of a cabinet is formed at the outer peripheral part of this key top member so as to protrude in the extension of both directions of a straight line which passes through two pushers respectively corresponding to the operation direction and the opposite direction against this one of the operation directions. SOLUTION: As for the height of the direction confronting with a pressing type switches 30a, 30b, 30c, 30d in the plurality of pushers 58a, 58b, 58c, 58d, the other pushers 58c, 58d excluding two pushers 58a, 58b are arranged so as to become lower than the two pushers 58a, 58b which correspond to one of the operation directions and the opposite direction against this one of the operation directions.
