description The waterproof member of the present disclosure is a waterproof member comprising a waterproof membrane configured to prevent entry of water while permitting sound and/or gas to pass therethrough, and a support layer having air permeability in a thickness direction thereof, wherein the member has a joining region where the waterproof membrane and the support layer are joined, and a non-joining region where the waterproof membrane and the support layer are spaced apart from each other, the non-joining region is surrounded by the joining region when viewed in a direction perpendicular to a main surface of the waterproof membrane, and a thickness of the support layer in the non-joining region is less than 100 µm. The waterproof member of the present disclosure is, for example, a waterproof sound-transmitting member including a waterproof sound-transmitting membrane and a support layer for the membrane and having improved sound transmission characteristics.
