Electrodes E1 and E2 are formed on a substrate SB1. Electrodes E3 to E10 are formed on the substrate SB1 to surround the electrodes E1 and E2. Conductive lines L1 and L2 extend over the substrate SB1 to sandwich the electrodes E6 and E7, and are connected to the electrodes E1 and E2. An insulating sheet, having a surface exposed to outside, covers the electrodes E1 to E10 and conductive lines L1 to L10. When a finger contacts the insulating sheet, if there are the electrodes E1 and E2 on a bottom side of a contact portion, capacitances of the electrical conductors EC1 and EC2 are changed. When the finger contacts the insulating sheet, if there are the electrodes E7 and the conductive line L1 that extends in the vicinity thereof on the bottom side of the contact portion, capacitances of the electrical conductors EC7 and EC1 are changed. |
