Photocurable resin composition, cured product thereof, and method for producing three-dimensional object

A photocurable resin composition comprising:

• a polyfunctional radical-polymerizable compound (A);
• a monofunctional radical-polymerizable compound (B);
• rubber particles (C) formed of a diene-based compound;
• and
• a radical polymerization initiator (D),
• wherein the polyfunctional radical-polymerizable compound (A) includes a polyfunctional urethane (meth)acrylate (a1) intramolecularly including at least two (meth)acryloyl groups and two urethane groups and including a structure represented by formula (1) or (2),
• a content of the polyfunctional urethane (meth)acrylate (a1) relative to 100 parts by mass of a total amount of the polyfunctional radical-polymerizable compound (A) and the monofunctional radical-polymerizable compound (B) is,
• 10 parts by mass or more and 60 parts by mass or less, and
• a content of the rubber particles (C) relative to 100 parts by mass of the total amount of the polyfunctional radical-polymerizable compound (A) and the monofunctional radical-polymerizable compound (B) is 2 parts by mass or more and less than 18 parts by mass,
• in formulas (1) and (2), R1 and R2 are each independently a hydrocarbon group including an alkylene group having 1 to 18 carbon atoms and n is 2 to 50.
