The present invention relates to a manufacturing method of health functional food which is easy to eat and has an excellent antioxidant effect by using a fermented product manufactured by kneading rice bran and embryo bud of rice, which are extracted from unpolished rice and pulverized to fine particles, mixing linseed powder to a steamed and sterilized mixture, then fermenting, drying and pulverizing. That is, the present invention is characterized in that the manufacturing method of health functional food using rice bran, embryo bud of rice and linseed comprises a first step of pulverizing a mixture of rice bran and embryo bud of rice, extracted from unpolished rice, into fine particles； a second step of making a dough by mixing water and milk with the mixture of rice bran and embryo bud of rice； a third step of sterilizing the dough by steaming； a fourth step of naturally cooling the steamed mixture of rice bran and embryo bud of rice； a fifth step of mixing particulates of linseed and lactobacillus to the naturally cooled mixture of rice bran and embryo buds of rice, stirring evenly and fermenting； a sixth step of drying the fermented mixture of rice bran, embryo bud of rice and linseed； and a seventh step of powderizing the dried fermented mixture.
