To provide a method for manufacturing a cooling head gear having excellent adhesion strength capable of making sufficiently thick the latex layer of the base part of a cooling waterway.

The manufacturing method contains a process of covering a mold 7 with a mesh-like reinforced cloth 51, a process of pressing in a latex solution 92 between the mold surface and the back face of the reinforced cloth, at the same time applying a latex solution 91 on the surface of the reinforced cloth, passing the latex solution between the mold surface and the back face of the reinforced cloth on the surface of the reinforced cloth, and ejecting air 10 in the reinforced cloth, and a process of applying a latex solidifying solution from the surface of the reinforced cloth while filling the latex solution 92 between the mold surface and the back face of the reinforced cloth.
