Abstract: An auxiliary sheet for laser dicing is provided, with which partial adhesion of a substrate film to a processing table is not caused even when dicing a workpiece by using a high output laser light and at a high scan speed, therefore, workability does not decline after that. An adhesive layer is stacked on one surface of the substrate film in the laser dicing auxiliary sheet and a functional layer is stacked on the other surface (a surface to contact with a processing chuck table during dicing), and the functional layer is formed by using a mixture containing metal oxide fine particles, in which an average particle diameter of the primary particle is 5 to 400 nm, and emulsion particles of a thermoplastic resin as a binder material.
