THICK FILM CAPACITOR

PROBLEM TO BE SOLVED: To provide a thick film capacitor with the conductor structure that is able to adjust the capacitance of the capacitor effectively, securely and easily. SOLUTION: The capacitor is provided with a lower conductor formed on an insulating board, a dielectric layer 4 formed on the lower conductor, an upper conductor 5 formed on the dielectric layer 4 and a protection layer 6 formed on the upper conductor layer 5 covering at least the dielectric layer 4. In this case, the conductor of either of the lower conductor or the upper conductor 5 is formed with the comb shape provided with a trunk part and branch parts connecting to it, a trimming groove 7 is formed for adjusting the capacitance, the dielectric layer 4 is formed overlapping the branch parts, the protecting layer 6 is formed to overlap the branch parts of the conductor at least and the trimming groove 7 is formed at the region where the protecting layer 6 of the conductor is not formed.
