1. A curable resin composition comprising components (A) to (E):
(A) monofunctional 2-(allyloxymethyl) acrylic acid or its ester;
(B) a polyfunctional radically polymerizable compound having an isocyanurate ring;
(C) a radically polymerizable compound;
(D) rubber particles; and
(E) a radical polymerization initiator,
wherein the component (A) is represented by formula (1)

OG Complex Work Unit Chemistry
in formula (1), R is hydrogen or a hydrocarbon group, the hydrocarbon group optionally has an ether bond, and the hydrocarbon group optionally has a substituent;
the component (B) is represented by formula (2)

OG Complex Work Unit Chemistry
in formula (2), two or more of X1, X2 and X3 independently have one or more radically polymerizable groups;
the component (C) is a radically polymerizable compound different from the component (A) and the component (B); and
when the sum of the component (A), the component (B) and the component (C) is 100 parts by mass, the component (B) is 20-50 parts by mass or more to 80 parts by mass or less and the component (C) is 0 parts by mass or more to 40 parts by mass or less.
