摘要： The present invention provides a small-sized capacitor module for use in an inverter, which is capable of suppressing the occurrence of unwanted inductance components in an electric connection path and which is suitable for a large current use. The present capacitor module is constituted by: mounting a plurality of ceramic capacitors 3 having first and second terminals 3a and 3b on the first surface 1 of a substrate 2; forming a first conductor 12 on the first surface of the substrate 2; forming a second conductor 14 on the second surface of the substrate 2; electrically connecting first and second terminals 3a and 3b to the first conductor 12 and the second conductor 14, respectively; forming, on the substrate 2, first and second terminal mounting portions where the respective first and second terminals of a switching module are mounted; and electrically connecting the first and second terminal mounting portions to the first and second conductors 12 and 14, respectively.
