Abstract
Abstract An electronic composite component is composed of a resistor element formed by a resistor film and a functional element such as a capacitor element which is electrically connected in parallel with the resistor element. The functional element has a body and a pair of terminal electrodes formed on respective end surfaces of the body. A serially extending electric insulation layer is formed on the surface of the body to partially cover the pair of terminal electrodes. This electric insulation layer is formed to selectively determine the distance between exposed regions of the terminal electrodes. The resistor film forming the resistor element is provided to partially cover and interconnect the exposed regions of the terminal electrodes and cross the boundary lines between the insulation layer and the exposed regions of the terminal electrodes, to electrically connect the pair of terminal electrodes with each other, through a resistance selectively determined according to the distance between the exposed regions of the terminal electrodes.
