An electronic part is disposed in a space defined by upper and lower frames joined together. The upper frame has an opening portion, and a hollow packing member is disposed in the opening portion to expose a specific region of the electronic part. The upper and lower frames are further covered with a cover having a window portion at a position corresponding to the hollow portion of the packing member. In this state, a thin film is formed through the hollow portion to coat the specific region of the electronic part. The thin film is not adhered to the upper and lower frames. Accordingly, the upper and lower frames can be reused to form the thin film onto another electronic part successively.
