ABSTRACT:
Disclosed are a thick-film capacitor and a chip-type composite electronic component. A pair of end electrodes are formed on the insulator substrate. A lower electrode is formed on the insulator substrate. A dielectric layer is formed on the lower electrode. An upper electrode formed on the dielectric layer. One of the lower electrode and the upper electrode has a broad-width portion having a width wider than the remaining portion thereof. The one of the lower and upper electrode at the broad-width portion is directly connected to one of the end electrodes. The thick-film capacitor is provided with a capacitor electrode arranged to provide positive connection, even where the width of the capacitor electrode is determined narrow to meet a small capacitance value.
