7 Claims

1. An electrostatic adsorption body adsorbing an object to be adsorbed with an electrostatic adsorption force, the electrostatic adsorption body comprising: a laminate sheet in which an insulator with a thickness of 20 to 200 μm, an electrode layer with a thickness of 1 to 20 μm, and a resin film with a thickness of 20 to 200 μm are sequentially laminated; and a power supply device that applies a voltage to the electrode layer, wherein the resin film at least has a tensile modulus of 1 MPa or more and less than 100 MPa and a volume resistivity of 1×10¹⁰to 10¹³Ω·cm, the electrode layer is composed of a bipolar electrode including a positive electrode and a negative electrode, and an object to be adsorbed is adsorbed using the resin film as an adsorption surface due to an electrostatic adsorption force that is generated by applying a voltage to the electrode layer.
