A multilayer made up of a support member with first electrodes including a plurality of electrodes arranged in parallel to each other and the second electrodes including a plurality of electrodes that are arranged parallel to each other so as to cross the first electrodes. The multilayer also includes a protective layer (a front member) that is provided opposite one side of the support member and with which a predetermined position pointing member is brought into contact, and a reinforcing material (a rear member) provided opposite the other side of the support member. A gas layer (space) is provided between the first electrodes or the second electrodes and at least one of the support member, the protective layer (the front member), and the reinforcing material (the rear member), thereby blocking electrical coupling paths that increase electrostatic capacitance.
