Abstract
The photocurable resin composition of the present invention has a reaction force at 10% compression of a cured product of the photocurable resin composition of 1 to 300 kPa and a reaction force at 50% compression of the cured product of the photocurable resin composition of 1 to 500 kPa, contains a hollow organic resin filler as a component (A), and does not contain a monofunctional acrylic monomer having a hydroxyl group.
