Document Type and Number:
Japanese Patent JP2019106440
Kind Code:
A
Abstract:
To provide an electret film including a transparent electret coating layer that can normally function.SOLUTION: An electret film 1 includes a base material layer 2, a transparent electret coating layer 3 that is a coated substance formed by coating an electret material on the base material layer 2, a transparent insulating layer 4, and a transparent conductive layer 5, in order on an upper side. The transparent insulating layer is a pressure-sensitive adhesive layer, and further includes a second transparent conductive layer. The second transparent conductive layer, the base material layer, the transparent electret coating layer, the transparent insulating layer and the transparent conductive layer are disposed in order toward one side in a thickness direction.SELECTED DRAWING: Figure 1
