A capacitor module that suppresses the occurrence of solder cracking includes a substrate having a first principal surface and a second principal surface opposite to each other in a thickness direction, and capacitor elements mounted on at least the first principal surface of the substrate, wherein the substrate has a first pad electrode solder-bonded to a first terminal electrode provided at one end side of the capacitor elements and a second pad electrode solder-bonded to a second terminal electrode provided at the other end side of the capacitor elements, and penetrating holes are provided at positions, which overlap a pair of boundary lines that define a boundary between at least a region between the first pad electrode and the second pad electrode and an outside of the region in a plan view, and pass through the substrate in the thickness direction.
