Capacitor module

A capacitor module comprising:

• a case defining an interior space and having an opening at a position opposed to a bottom surface thereof;
• a sealing resin in the interior space of the case;
• one or more capacitors in the sealing resin in the interior space of the case, each of the one or more capacitors having a first electrode and a second electrode;
• a first bus bar having a first contact portion that is in contact with the first electrode of the one or more capacitors, a first buried portion in the sealing resin and extending from the first contact portion, and a first exposed portion that extends from the first buried portion outside the sealing resin;
• and
• a second bus bar having a second contact portion that is in contact with the second electrode of the one or more capacitors, a second buried portion in the sealing resin and extending from the second contact portion, and a second exposed portion that extends from the second buried portion outside the sealing resin,
• wherein at least one of the first contact portion, the second contact portion, the first buried portion, and the second buried portion define one or more through holes that are filled with the sealing resin or include one or more protrusions surrounded by the sealing resin.
