Electrostatic sensor

1. An electrostatic sensor comprising:

a decoration portion divided into a plurality of decoration pieces formed of a metal-based material, the plurality of decoration pieces being provided in an attachment target member;

an insulation substrate that is arranged in a back portion in each of the plurality of decoration pieces; and

a plurality of electrodes that are arranged on the insulation substrate and that individually detect a detection target which comes into contact with or approaches the decoration pieces,

wherein the plurality of decoration pieces are divided according to arrangement of the plurality of electrodes, and

wherein the plurality of respective electrodes and the decoration pieces divided according to the arrangement of the electrodes are short-circuited from each other.

2. The electrostatic sensor according to claim 1 ,

wherein the plurality of decoration pieces are formed of at least one of a transparent electrode or a foil tape made of a conductor.

3. The electrostatic sensor according to claim 1 ,

wherein the plurality of decoration pieces are provided in an attachment target member,

the plurality of electrodes individually detect a detection target which comes into contact with or approaches the decoration portion, and

wherein the plurality of respective electrodes are arranged in a state in which the electrodes do not occupy a space formed by projection of the decoration portion in a plate thickness direction.

4. The electrostatic sensor according to claim 1 ,

wherein the plurality of electrodes configure different channels, respectively.

5. The electrostatic sensor according to claim 1 ,

wherein the plurality of decoration pieces presents a thickness in a thickness direction of the attachment target member, and

wherein the thickness of the plurality of the decoration pieces is equal to a thickness of the attachment target member at a respective location at which a respective decoration piece is provided.
