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 first and second external electrodes separated from each other in a length direction. The resistance element includes a base portion, a resistor disposed on an upper surface of the base portion, a protective film and first and second upper surface conductors. The first and second upper surface conductors are separated from each other in the length direction and the resistor is between the first and second upper surface conductors. The protective film covers the resistor. Dimensions in the height direction from the upper surface of the base portion to exposed surfaces of a pair of end portions in the length direction of the protective film are smaller than a dimension in the height direction from the upper surface of the base portion to an exposed surface of the protective film in the center portion.
