Abstract: A surface-mountable composite electronic part comprising a capacitor element which includes a dielectric ceramic member and a film resistor combined therewith for forming an RC circuit. A plurality of external terminals are formed on both end surfaces of the capacitor element for extracting capacitance, while a plurality of wiring patterns are formed on a first major surface of the capacitor element to be connected with the external terminals. The film resistor is formed on the first major surface of the capacitor element on a protective film made of a glass material, and connects a pair of the wiring patterns with each other. When the film resistor is trimmed with a laser beam, the protective film prevents the dielectric ceramic member forming the capacitor element from being harmed by the laser beam.
