摘要:An electronic element having at least a pair of electrodes (4,5) is formed on a substrate (1). A varistor element (10) is formed on the substrate, the varistor element including a pair of electrodes (11, 12) and a varistor insulating film (13). When a surge voltage is applied across the pair of electrodes (11, 12) of the varistor element (10), a surge current flows through the varistor insulating film (13). One electrode (11) of the varistor element is connected to one electrode (4) of the electronic element, and the other electrode (12) of the varistor element is connected to the other electrode (5) of the electronic element. Thus, a countermeasure against electrostatic surges is provided.
