Patent ID: 7007943

Claim:
An absorption belt capable of absorbing an object, comprising: a base layer; an insulating layer on said base layer; a plurality of electrodes embedded alternately with positive and negative in said insulating layer; and a plurality of layers for covering each of said electrodes, at least two of said layers having different volume resistivities, said plurality of layers including a first layer directly covering said plurality of electrodes and said insulating layer and a second layer disposed above said first layer, said second layer having a volume resistivity Ra 2 smaller than a volume resistivity Ra 1 of said first layer, a volume resistivity of a resin which is a main ingredient of said second layer before a control of resistance being 1.0×10 16 Ω·cm or less, wherein a surface of each of said plurality of electrodes, which faces in a direction of a thickness of said absorption belt, is in contact with said first layer or said base layer, a surface of each of said plurality of electrodes, which faces in a direction perpendicular to the direction of the thickness of said absorption belt, is in contact with said insulating layer, said plurality of electrodes and said insulating layer are arranged alternately with each other in the direction perpendicular to the direction of the thickness of said absorption belt, and respective volume resistivities of said insulating layer and said base layer are larger than that of said first layer.
