Abstract
A method for producing a heat conductive member includes the steps of: preparing a hollow type heat recovery member having: an inner peripheral surface and an outer peripheral surface in an axial direction; and a first end face and a second end face in a direction orthogonal to the axial direction; inserting an inner cylindrical member into a hollow portion formed in an inner region of the inner peripheral surface; and subjecting the inner cylindrical member to plastic working, and fitting at least a part of the inner cylindrical member to at least a part of one or more selected from the inner peripheral surface, the first end face, and the second end face of the heat recovery member.
