Abstract

A resist film for protecting a circuit pattern is coated onto a circuit pattern formed on a circuit board, and further, a part of the resist film with which another unit comes into contact is coated with a thermosetting film. Namely, the other unit is brought into contact with a part of the circuit pattern coated with the thermosetting film, and thus, the other unit and the resist film do not come into contact with each other directly, regardless of whether or not the other unit has a high temperature.
