Abstract

A heat conductor includes a first layer containing a first resin component and first flake graphite fillers each having a basal plane; and a second layer containing a second resin component and second flake graphite fillers each having a basal plane. The heat conductor is a laminate including the first layer and the second layer, an average of first angles in the first layer is 35 degrees or smaller, each of the first angles is an acute angle between the basal plane of a corresponding one of the first flake graphite fillers and a first laminated surface of the laminate, an average of second angles in the second layer ranges from 55 degrees to 90 degrees, and each of the second angles is an acute angle between the basal plane of a corresponding one of the second flake graphite fillers and a second laminated surface of the laminate.
