ABSTRACT:
A square chip resistor in which, when the protective glass layers are fired, a powder of an inorganic material such as alumina or the like having a greater thermal expansion coefficient than glass is mixed into glass paste to thereby adjust the thermal expansion coefficient of the protective glass layers. This makes it possible to prevent generation of any crack on the glass surface due to a stress produced by a difference between the thermal expansion coefficients of the glass layer and an alumina substrate.
