The present invention provides an acid-modified polypropylene resin that can be used as an adhesive capable of bonding a polyolefin resin and a polar resin with sufficient force, a method for producing the same, and a resin composition using the acid-modified polypropylene resin. An acid-modified polypropylene resin obtained by grafting an organic acid component onto a polypropylene resin, wherein the polypropylene resin is an isotactic polypropylene resin, and the graft amount X (wt) of the organic acid component in the acid-modified polypropylene resin. %) Is in the range of 1.0 wt% to 20.0 wt%, and the acid-modified polypropylene resin satisfies the melt flow rate Y (g / 10 min) of the acid-modified polypropylene resin as Y≤18.5exp (0.82X). Resin, method for producing acid-modified polypropylene resin, and resin composition and laminate using the same. [Selection figure] None |
