ABSTRACT:
A chip type thick film capacitor is provided which comprises an insulating chip (11) serving as a substrate and having a head surface (11a). The chip head surface (11a) is formed with a first lead electrode (12) and a second lead electrode (13) spaced from the first lead electrode (12). The chip head surface (11a) is also formed with a first capacitor electrode (14) in electrical conduction with the first lead electrode (12). The chip head surface (11a) is further formed with an auxiliary electrode (20) which is held in electrical conduction with the second lead electrode (13) but spaced from the first capacitor electrode (14) by a predetermined distance (D1). A dielectric layer (15) is formed on the first capacitor electrode (14), and a second capacitor electrode (16) is formed on the dielectric layer (15) in electrical conduction with the auxiliary electrode (20).
