1. A radical polymerizable putty-like resin composition comprising
a resin component containing a radical reactive resin (A) and a radical polymerizable unsaturated monomer (B) having a (meth)acryloyl group in a molecule thereof,
an aromatic tertiary amine (C) represented by the following general formula (I), an organic peroxide (D), and
a filler (E):

OG Complex Work Unit Chemistry
wherein,
R1 is a hydrogen atom, a methyl group, or a methoxy group; and R2 and R3 are each independently an alkyl group having 1 to 20 carbon atoms or a hydroxyalkyl group having 1 to 20 carbon atoms,
wherein the resin composition further comprises a plasticizer (F) and an internal release agent (G),
and the content of the plasticizer (F) is from 5 to 200 parts by mass based on 100 parts by mass of the resin component,
and the internal release agent (G) is at least one selected from the group consisting of a phosphoric acid ester and a fluorine-containing release agent,
and the internal release agent (G) is contained in an amount of 0.01 to 1 part by mass based on 100 parts by mass of the resin component,
and the resin composition has a thixo index (TI) of 3.5 or more.
