A photocurable resin composition contains an acrylate-based oligomer component as component (a), an acrylic-based monomer component as component (b), a plasticizer component as component (c), and a photopolymerization initiator component as component (d). The total amount of the component (a) and the component (b) contained in the photocurable resin composition is 25 to 80% by mass, and the amount of the plasticizer component as the component (c) contained in the photocurable resin composition is 65 to 10% by mass. The component (c) contains a solid tackifier and a liquid plasticizing component, and the mass ratio of the tackifier to the liquid plasticizing component is in the range of 60 to 30 : 30 to 10.
