PROBLEM TO BE SOLVED: To provide a method for producing a modified polypropylene with a high modification efficiency. SOLUTION: This method produces a modified polypropylene by melt kneading, with a kneader, (A) polypropylene particles having a particle size of 1,200μm or lower, (B) at least one compound selected from the group consisting of compounds each having (i) at least one kind of unsaturated group, i.e., carbon-carbon double bond or carbon-carbon triple bond, and (ii) at least one kind of polar group and compounds each having (iii) an OR group (wherein R is H or an alkyl, aryl, acyl or carbonyldioxy group) and (iv) at least two, same or different, functional groups selected from among carboxylic acid, acid halide, acid anhydride, acid halide anhydride, acid ester, acid amide, imide, and amino groups, and (C) a peroxide.
