Abstract: Provided is the following film for a pressure-sensitive adhesive tape in which a non-pressure-sensitive adhesive layer is provided on a base material film. In the case where dicing or the like is performed by performing adsorption fixation to a fixing base with a negative pressure, the occurrence of excessive close adhesion due to, for example, the heat generation of the base can be effectively suppressed. In addition, the non-pressure-sensitive adhesive layer is provided on the base material film, and hence blocking in a roll shape is effectively suppressed, the film for a pressure-sensitive adhesive tape does not tear or break upon its unwinding from the roll shape, conformity between the non-pressure-sensitive adhesive layer and the base material film is good, and followability to a deformation such as stretching is good. Also provided is a pressure-sensitive adhesive tape including such film for a pressure-sensitive adhesive tape. The film for a pressure-sensitive adhesive tape is a film for a pressure-sensitive adhesive tape, including a non-pressure-sensitive adhesive layer on one surface of a plastic film, in which: the non-pressure-sensitive adhesive layer includes a mixed layer of a silicone and a (meth)acrylic polymer; and the (meth)acrylic polymer has a calculated Tg of 10° C. or more.
