1. A waterproof sound-permitting sheet comprising:
a porous nanoweb layer formed of accumulation of ultra-fine fiber strands and having a plurality of first pores, wherein the ultra-fine fiber strands have an average diameter in a range of 0.3-1.5 μm, the first pores have an average size in a range of 1.5 to μm, and the ultra-fine fiber strands are formed of a polymer material and a color pigment; and a double-sided adhesive tape stacked along an edge of the porous nanoweb layer, wherein the double-sided adhesive tape comprises: a substrate formed in a nanoweb form and having a plurality of second pores; a first adhesive layer formed on a first surface of the substrate; and a second adhesive layer formed on a second surface of the substrate, the second surface being opposite to the first surface. |
