The present invention relates to a non-oriented electrical steel sheet adhesive coating composition including the constituent elements below, a non-oriented electrical steel sheet product, and a manufacturing method thereof. The non-oriented electrical steel sheet adhesive coating composition includes: a first component including an organic/inorganic composite; and a second component including a composite metal phosphate, wherein the organic/inorganic composite is formed by having inorganic nanoparticles chemically substituted with some functional groups in an organic resin, the organic resin is one, or two or more, selected from an epoxy-based resin, an ester-based resin, an acrylic resin, a styrene-based resin, a urethane-based resin, and an ethylene-based resin, and the inorganic nanoparticles are one, or two or more, selected from SiO, AlO, TiO, MgO, ZnO, and ZrO. 1. A non-oriented electrical steel sheet adhesive coating composition , being a composition comprising:a first component including an organic/inorganic composite; anda second component including a composite metal phosphate,wherein the composition includes 70 to 99 wt % of the first component and 1 to 30 wt % of the second component based on a total amount, 100 wt %, of the composition,the organic/inorganic composite is formed by having inorganic nanoparticles chemically substituted with some functional groups in an organic resin,the organic resin is one, or two or more, selected from an epoxy-based resin, an ester-based resin, an acrylic resin, a styrene-based resin, a urethane-based resin, and an ethylene-based resin, and{'sub': 2', '2', '3', '2', '2, 'the inorganic nanoparticles are one, or two or more, selected from SiO, AlO, TiO, MgO, ZnO, and ZrO,'}2. The non-oriented electrical steel sheet adhesive coating composition of claim 1 , wherein the second component is one composite metal phosphate or a mixture of two or more selected from aluminum phosphate monobasic (Al(HPO)) claim 1 , cobalt ...
