Thin film capacitor and electronic circuit board

Abstract

A thin film capacitor for which electrode conductivity is high and electrode irregularities are unlikely to be generate even if the capacitor if heated up to 700° C. This thin film capacitor has a first electrode, a dielectric layer, and a second electrode. The dielectric layer contains an ABO2N-type oxynitride. The nitrogen concentration of the part of the dielectric layer that contacts the first electrode is no more than half the nitrogen concentration of the center part of the dielectric layer.
