WIPO Patent Application WO/2019/078133
Kind Code:
A1
Abstract:
Provided is a roll-type element in which a wound multilayer film has less size variation in the diameter thereof. This roll-type element is formed by winding a multilayer film 2, wherein: the multilayer film 2 has a first insulating layer 3, a second insulating layer 4 formed on the first insulating layer 3, and an electrode layer 5 formed on the second insulating layer 4; the layer having the least thickness among the first insulating layer 3, the second insulating layer 4, and the electrode layer 5 is less than 10 µm thick; and the multilayer film 2 is wound on a core 1. For example, the first insulating layer 3 is made of a material which swells by absorbing a liquid. A third insulating layer 6 is optionally formed on the electrode layer 5.
