PROBLEM TO BE SOLVED: To provide a casting method and a casting product with which the lightening of the cast product is easily obtained and realized at a low cost. SOLUTION: A preform 1 compression-deformable composed of fiber material having heat resistance, is positioning-set in a forming space 22, and molten metal 2 is poured at a low pressure into the forming space 22 at the pressure setting so as not to penetrate the molten metal 2 into the preform 1, and the molten metal 2 is filled up along the outer surface of the preform 1 between the preform 1 and metallic molds 20, 21.
