HEAT RELEASE MEMBER

摘要

A heat release member (1) is configured such that a metallic plate (10), which is bent along folding starting lines (11) into a corrugated shape, is disposed such that the folding starting lines (11) are aligned in the axial direction and so that the entire metallic plate (10) has a cylindrical shape. The heat release member (1) has fin sections (13) which are arranged radially in the radial direction of the cylindrical shape. Adjacent fin sections (13) are connected to each other on the inner peripheral side (101) and the outer peripheral side (102) of the cylindrical shape. The heat release member (1) has a joining end (12) at one end (115) in the axial direction (X) of the cylindrically shaped heat release member (1). The heat release member (1) is used while the joining end (12) side is joined to a heat generation member.
