COMPOSITE ELECTRONIC COMPONENT AND RESISTANCE ELEMENT

摘要

A composite electronic component includes an electronic element and a resistance element in a height direction. The electronic element includes an electronic element body, and a first and second external electrodes separated from each other in a length direction. The resistance element includes a base portion, a resistor disposed on the upper surface of the base portion, a protective film, and first to third upper surface conductors. The first and second upper surface conductors are separated from each other in the length direction, and the resistor and the third upper surface conductor connected thereto are located between the first and the second upper surface conductors. Dimensions in the height direction from the upper surface of the base portion to the surfaces of the first and second upper surface conductors are larger than dimension in the height direction from the upper surface of the base portion to the surface of the portion overlapped with the protective film in the height direction of the third upper surface conductor.
