PROBLEM TO BE SOLVED: To provide an adhesive sheet for dicing to prevent the deterioration of product fidelity or the disadvantage of cost performance, to suppress the generation of thread-like dusts at the time of dicing, to prevent a film from being torn in an expand process, and to reduce the generation of chipping. SOLUTION: In an adhesive sheet (1) for dicing constituted by forming an adhesive layer (12) on at least one face of a base material film (11), the base material film (11) is a multi-layer film with two or more layers, and at least the two layers of the multi-layer film contain olefin system thermoplastic elastomer containing propylene as polymeric components whose melting peak temperatures range from 120°C to 170°C, and the olefin system thermoplastic elastomer contained in at least the two layers is provided with different propylene content.
