Waterproof member and electronic device

Abstract

The waterproof member of the present disclosure includes 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. The waterproof 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. A thickness of the support layer in the non-joining region is 500 μm or less. A spacing distance between the waterproof membrane and the support layer in the non-joining region is 150 μm or less. An air resistance in an in-plane direction of the support layer is greater than 80,000 seconds/100 mL.

Dependencies are inferred from the claim text.
