Abstract
Provided is an electrostatic adsorption body capable of exhibiting a high adsorption force, especially with respect to a highly insulative sheet-like object to be adsorbed, such as a cloth, while using an electrical adsorption force. This electrostatic adsorption body, which uses electrostatic force to adsorb an object to be adsorbed, is provided with: a laminate sheet in which a 20-200 μm-thick insulator, a 1-20 μm-thick electrode layer, and a 20-200 μm-thick resin film 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 1×1010-1013 Ω 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.
