A mouse which can be grasped without a brachial tendon twisted, and moved with the palm supported in that condition and without causing pain nor fatigue to the user. A mouse body (1) is provided with a button (2) for a pressing operation, a cable (4) for connection between the mouse body (1) and an information processor such as a PC and for use as an input-information transmitting medium, a grip (10) that the user can take hold of in relaxation without the brachial tendon twisted, and a support (6) on which the user rests his palm. On the surface of the grip (10) are formed irregularities almost matching those on the palm surface of the right hand taking hold of the grip to prevent a strong pressure from acting on a particular part of the gripping palm. Since the user can hold the grip (10) in a relaxed manner with the brachial tendon untwisted and rest his palm on the support (6), the user can use the mouse comfortably without placing loads on the hand and arm.
