PROBLEM TO BE SOLVED: To develop a mold for the molding of a concrete product which can manufacture the product of a complicated shape at a low cost, and also, is excellent in strength and rigidity as well. SOLUTION: A notched section is provided at a part of the main body made of a metal. A core material comprising a surface material made of a metal having numerous holes such as a punching metal or an expand metal is fixed to the notched section, and a section made of a resin is formed in a manner to cover the core material. The strength and the rigidity are ensured by the sections made of the metal. The resin section can easily mold the complicated shape, and the strength and the rigidity become sufficient as well by the core material. COPYRIGHT: (C)2007,JPO&INPIT
