Disclosed is a cationically polymerizable resin composition which includes an oxetane-ring-containing vinyl ether compound (A) and/or an alicyclic-epoxy-containing vinyl ether compound (B); and an oligomer or polymer (C) having a molecular weight of 500 or more, being liquid at 0° C., and containing at least one of structures represented by following Formulae (1a) to (1f), wherein R
x
represents hydrogen atom or methyl group; R
1
to R
3
each independently represent a hydrocarbon group having 1 to 5 carbon atoms; “a” is an integer of from 0 to 5; and “b” is 1 or 2. This cationically polymerizable resin composition has a low viscosity, is easy to work, cures extremely rapidly upon irradiation with light, and can give a cured object excellent in flexibility, thermal stability, and bendability after heat treatment.
