Abstract
The present invention provides a waterproof member suitable for inhibiting persistence of deformation of a waterproof membrane due to application of water pressure and a waterproof case including the waterproof member. A waterproof member is configured to be disposed to cover an opening of an object having an opening surface having the opening. The waterproof member includes a waterproof membrane having a first principal surface that faces the opening when disposed to cover the opening. The first principal surface of the waterproof membrane has a function of reducing adhesion to a surface facing the principal surface of the waterproof membrane.
Claims23
A waterproof member configured to be disposed to cover an opening of an object having an opening surface having the opening, comprising
- a waterproof membrane having a first principal surface that faces the opening when the waterproof member is disposed to cover the opening, wherein
- the first principal surface of the waterproof membrane has a function of reducing adhesion to a surface that faces the first principal surface of the waterproof membrane.
