1. A grip comprising:
a core that has electrical conductivity, the core being disposed inside the grip for forming a structure of the grip;
a sensing electrode for detecting a biological signal of a user, the sensing electrode being exposed on a surface of the grip, and being connected with the core via a voltage follower circuit; and
a ground electrode that is connected with a reference voltage portion,
wherein:
the core, the sensing electrode and the ground electrode are insulated from one another; and
the ground electrode is located at such a position that the core is able to reduce a parasitic capacitance which exists between the ground electrode and the sensing electrode.
