Abstract
An organic insulating coating formed on a substrate is composed of two layers of a first parylene coating and a second parylene coating. Heat treatment is performed to at least the first parylene coating after being formed, at a temperature below 125° C. for two hours. Then the second parylene coating is formed on the first parylene coating. Occurrence of pinholes is thus prevented at least in one of the two layers of the organic coatings, with the result that insulating properties of the coatings are improved.
