The capacitance sensor has the multiple electrodes which output the electric information which responds to the capacitance which becomes settled due to the surface of the capacitance sensor and the distance between the conductors. And, among the multiple electrodes, the electrode which has 1st parasitic capacity and, the electrode which has the 2nd parasitic capacity which differs from 1st parasitic capacity, following to the specified layout pattern which differs from the living body information of the region which is read with the capacitance sensor it is laid out.静電容量センサは、静電容量センサの表面と導体間の距離によって定まる静電容量に応じた電気信号を出力する複数の電極を有する。そして、複数の電極のうち、第1の寄生容量を持つ電極と、第1の寄生容量と異なる第2の寄生容量を持つ電極が、静電容量センサで読み取られる部位の生体情報と異なる所定の配置パターンに従って配置される。
