Abstract: Provided are an electric appliance and a method of manufacturing the same, the electric appliance having a smaller size and a reduced overall weight by preventing a fluid from flowing into a space unrelated to a heating component in a state where the fluid fills its case. The electric appliance includes: a case including a first space and a second space communicated to each other; a first component disposed in the first space; a second component disposed in the second space; a connection portion electrically connecting the first component and the second component to each other; and a potting pattern including a resin material and formed in the first space.

Abstract: Disclosed is a radio wave penetration-type multilayer optical coating. The coating includes: a transparent first resin layer; an optical coating with a multilayer structure formed by alternately forming TiO2 and SiO2 on the first resin layer; and an opaque second resin layer formed on the optical coating.
