Such a mottled porous pressure-sensitive adhesive layer has an advantage that the pores thereof are less likely to be crushed by compression by lamination or the like, as compared with the above-mentioned fibrous molded article. Further, it has an advantage that a porous adhesive layer can be formed so as to be more nearly applied to the entire surface, and floating does not easily occur in adhesion to a soft base material or an adherend that is easily stretchable and contractible. The basis weight of the mottled porous adhesive layer can be the same as that of the fibrous material.

The weight of the entire tape can be reduced. It also has the advantage that the supporting substrate does not require heat resistance, and that it has excellent fineness and even distribution of pores, has little unevenness in air permeability and adhesive force, and can form an adhesive tape with cushioning and heat retaining properties. ing.
