摘要： A laminate body includes a plurality of ceramic layers and capacitor conductors embedded in the laminate body so as to be opposed to each other via one of the ceramic layers. The capacitor conductors are made of an Al-based material, and the capacitor conductors include narrow portions, respectively, which function as fuse elements. The narrow portions have an average width smaller than an average width of portions of the capacitor conductors other than the narrow portions. As a result, the electronic component has an improved capability to protect its function as a capacitor when a short circuit occurs between capacitor conductors.
