CAPACITOR MODULE

The present invention relates to a capacitor module capable of configuring a side wall case by adjusting the number of side walls to correspond to the number of cylindrical capacitors. The capacitor module comprises a plurality of cylindrical capacitors; a side wall case in which a plurality of the cylindrical capacitors are stored on the inner side by being arranged in m×n and which comprises a plurality of side walls; and a cover case covering the side wall case by being coupled to the upper part of the lower part of the side wall case, respectively. Channel grooves are formed at the end on one side of the side walls, respectively, and a key member is formed at the end on the other side. The key member is inserted and connected to the channel groove and supports the cylindrical capacitor arranged in m×n.
