1. A multilayer sheet disposed at least between a plurality of heat sources and capable of conducting heat from the heat sources, comprising:
a rubber sheet made of a rubber-like elastic body;
heat insulating sheets laminated on both surfaces of the rubber sheet and capable of reducing heat conduction between the plurality of adjacent heat sources; and
first heat conductive sheets laminated outside the heat insulating sheets in a separated manner and having higher heat conductivity than that of the rubber sheet and the heat insulating sheets,
wherein
the heat insulating sheets wrap the rubber sheet and include bonded parts extending outward beyond an edge part of the rubber sheet, and
the bonded parts of the heat insulating sheet are bonded with a continuous area of cavities and protrusions.
