To provide a form material which is good in surface water resistance and releasability from a concrete skeleton, and excellent in uniform preheating performance of a form basic material, and to provide a method for producing the form material.
According to the method for producing the form material, the form basic material 1 is made of a mixed material which is prepared such that a mixing ratio of vegetable fibers to thermoplastic fibers is set within the range of 70/30 to 40/60, and both front and rear surfaces of the form basic material 1 are covered with air-permeable cloth-like materials 2 made of thermoplastic fibers. Then, the form basic material 1 covered with the cloth-like materials 2 are heated and pressurized, to thereby produce integrally the form material.
