The present invention aims to provide a dicing die bond film that is capable of suppressing peeling of the dicing die bond film from a dicing ring. The present invention provides a dicing die bond film in which the pressure-sensitive adhesive layer contains a polymer formed by performing an addition reaction on a specific acrylic polymer with a specific isocyanate compound, and a specific crosslinking agent, and the specific peeling adhesive power of a portion of the pressure-sensitive adhesive layer where the dicing ring is pasted is 1.0 N/20 mm tape width or more and 10.0 N/20 mm tape width or less, the tensile storage modulus at 23° C. of the portion where the dicing ring is pasted is 0.05 MPa or more and less than 0.4 MPa, and the die bond film is pasted to the pressure-sensitive adhesive layer after irradiation with an ultraviolet ray. |
