PURPOSE: To provide a trimming capacitor in which trimming electrodes and an internal electrode are formed on one surface side and has such a structure that can prevent the occurrence of warps at the time of sintering.
CONSTITUTION: A trimming capacitor is provided with trimming electrodes 3 formed on the surface of a dielectric 1 and an internal electrode 2 formed in the shape of a layer in the dielectric 1 near the surface of the dielectric 1. The capacitor is also provided built-in dummy electrodes 5 for preventing the occurrence of warps at the time of sintering. The electrodes 5 are provided at a depth from 0.05mm to 40% of the thickness of a chip from the surface of the dielectric 1 opposite to the surface of the dielectric 1 on which the electrode 3 is formed. Since the capacitor is provided with the built-in dummy electrodes 5, the electrodes 5 do not touch a conductor pattern on a substrate when the capacitor is mounted on the substrate. When multiple dummy electrodes 5 are provided in the direction of lamination and layers of the dielectric 1 are put between each dummy electrode 5, the occurrence of voids can be prevented in the capacitor.
