PROBLEM TO BE SOLVED: To provide a dicing die bond sheet from which a protecting film can easily be peeled without weakening the sticking force of a sticky agent and which can sufficiently stick a dicing ring and facilitates the subsequent dicing process, and the like. SOLUTION: This dicing die bond sheet prepared by laminating an adhesive (die bonding material) 2 having a prescribed planar view shape, a sticking agent which covers the adhesive 2, has a larger size than that of the adhesive 2, and has a peripheral portion (used as a dicing ring-loading portion) not overlapping with the adhesive, and a substrate film overlapping with the sticking agent in this order to one side of a protecting film 1 is characterized in that a projected portion projected in a state contacting with or approaching the outer periphery of the sticking agent at at least one position on the planar view is formed in the outer periphery of the adhesive 2.
