Abstract: The sound absorbing material according to the present invention is formed by laminating a porous sound absorber and two or more sheets of a nonwoven fabric one on another. The nonwoven fabric has a plurality of drawn filaments arranged and oriented in one direction. The mode value of the diameter distribution of the plurality of filaments is in the range of 1 to 4 μm. The grammage of the nonwoven fabric is in the range of 5 to 40 g/m2. The sound absorbing material according to the present invention provides high sound absorption performance in a predetermined low frequency band of 6000 Hz or less, and still remains light in weight and flexible enough and easy enough to handle to be substantially comparable to the porous sound absorber.

Abstract: A substrate 2 of an adhesive tape 1 includes a mesh structure made of thermoplastic resin. The mesh structure has a structure in which multiple first fibers drawn in a first direction corresponding to a length direction of the adhesive tape and multiple second fibers drawn in a second direction corresponding to a width direction of the adhesive tape are layered or woven. (a) A first fiber has a thickness of 0.04 mm or less, and a width of 0.6 mm or less, (b) a second fiber has a thickness greater than that of the first fiber, and a width greater than or equal to that of the first fiber, (c) the mesh structure has a tensile strength in the first direction of from 130 to 250 N/50 mm, (d) the mesh structure has a bending resistance in the first direction obtained by a cantilever test of from 40 to 80 mm, and (e) the mesh structure has a bending resistance in the second direction obtained by the cantilever test of from 65 to 95 mm.
