Abstract: The present invention relates to an adhesive tape comprising a base material layer made of a flat yarn cloth, a first film layer made of a thermoplastic resin film layered on one surface of the base material layer, a second film layer made of a thermoplastic resin film layered on the other surface of the base material layer, and an adhesive layer layered on the surface of the second film layer opposite to the base material layer, in which the first film layer and the second film layer both contains a pigment.

Abstract: The present invention relates to a double-sided pressure-sensitive adhesive tape excellent in good balance of both flame retardance and pressure-sensitive adhesive properties, comprising a layer structure of a pressure-sensitive adhesive layer (I), a substrate, and a pressure-sensitive adhesive layer (II) in this order, in which a proportion (Y/X) of a thickness (X) of the pressure-sensitive adhesive layer (I) and a thickness (Y) of the pressure-sensitive adhesive layer (II) is more than 1.00 and less than 2.00.

Abstract: The present invention relates to a double-sided pressure-sensitive adhesive tape comprising a layer structure of a pressure-sensitive adhesive layer (IA), a substrate, and a pressure-sensitive adhesive layer (IIA) in this order, wherein a flame retardant (C) is contained in at least one of the pressure-sensitive adhesive layer (IA) and the pressure-sensitive adhesive layer (IIA), a content of the flame retardant (C) is 10 parts by mass or less with respect to 100 parts by mass of a total amount of the resin components in the pressure-sensitive adhesive layer (IA) and the pressure-sensitive adhesive layer (IIA), and a proportion (YA/XA) of a thickness (XA) of the pressure-sensitive adhesive layer (IA) and a thickness (YA) of the pressure-sensitive adhesive layer (IIA) is 2.00 or more.
