Abstract
A layered sheet 10 includes a substrate layer 1, and surface layers 2 and 3 configured to be layered on at least one surface of the substrate layer 1. The substrate layer 1 contains a first thermoplastic resin and inorganic fillers. The surface layers 2 and 3 contain a second thermoplastic resin and a conductive material. A content of the inorganic fillers in the substrate layer 1 is 0.3 to 28 mass % based on a total amount of the substrate layer.
