Resin composition for molding and molded article

A resin composition for molding, comprising:

• a chlorinated polyvinyl chloride resin;
• a polyvinyl chloride resin;
• and
• a melt additive,
• the resin composition having an area ratio of a peak B observed in a range of 0.6 to 1.0 ppm to a peak A observed in a range of 9.5 to 10 ppm (Area of peak B/Area of peak A) of 1 to 1,000 when a 1H NMR spectrum is measured by solution NMR,
• an amount of the polyvinyl chloride resin being 0.5 to 30 parts by mass based on 100 parts by mass of the chlorinated polyvinyl chloride resin,
• the melt additive containing structural units represented by the following formulas (1) to (3),
• wherein in the formula (2), X represents at least one selected from the group consisting of an alkyl group, a halogen group, a carboxy group, a hydroxy group, an acetyl group, an acryloyl group, a cyano group, an acrylamide group, a phenyl group, and an ether group, and
• the melt additive having a weight average molecular weight of 1,000 to 1,000,000 and having a melting point of 60 to 150° C.
