Abstract
A gouging tool is introduced at a slope angle θ to form small, low fins at a position shifted inward from an edge of a surface of a metal plate having a high coefficient of thermal conductivity; and the small fins are sequentially formed in a plural number at a fixed pitch until a blade section of the gouging tool reaches a prescribed depth. A fin formation step in which plate-shaped heat-radiating fins are integrally formed upright by the gouging tool is subsequently repeated in sequential manner following formation of the small fins, and the heat-radiating fins are continuously formed in a plural number in the metal plate. Heat-radiating fins of a heat radiator can be formed by a gouging tool without generating scrap.
