Claim 0:
1. A resin composition for molding comprising:
a chlorinated polyvinyl chloride;
an acrylic processing aid; and
an impact resistance modifier,
the acrylic processing aid comprising an acrylic resin having a weight average molecular weight of 1,100,000 to 2,400,000,
a diene component content of a polymer constituting the impact resistance modifier is 35 to 65% by mass,
the resin composition comprising the acrylic processing aid in an amount of 0.2 to 10 parts by mass and the impact resistance modifier in an amount of 5.5 to 8.0 parts by mass relative to 100 parts by mass of the chlorinated polyvinyl chloride, and
the chlorinated polyvinyl chloride having structural units (a) to (c) represented by the following formulae (a) to (c):

—CCl2—  (a),

—CHCl—  (b),

—CH2—  (c),

wherein a proportion of the structural unit (a) is 17.5 mol % or less, a proportion of the structural unit (b) is 46.0 mol % or more, and a proportion of the structural unit (c) is 37.0 mol % or less, relative to a total number of moles of the structural units (a), (b), and (c).
