Patent ID: 8315031

Claim:
A case mold type capacitor comprising: a capacitor module comprising a capacitor element having a first electrode and a second electrode; a pair of terminals each of which is connected to the first electrode and the second electrode of the capacitor element, respectively; and a molding resin embedding the capacitor element in a manner that the terminals are partially exposed out of the resin, wherein the molding resin has an epoxy resin that contains an inorganic filler and a molecular sieve mixed in the epoxy resin, and wherein a mixing amount of the molecular sieve with respect to 100 parts by weight of the epoxy resin containing the inorganic filler is as follows: a mixing amount more than 0 part by weight and not more than 5.5 parts by weight for the molecular sieve with a pore diameter not less than 2.7 Å and not more than 3.3 Å; a mixing amount more than 0 part by weight and not more than 6.0 parts by weight for the molecular sieve with a pore diameter not less than 3.7 Å and not more than 4.3 Å; a mixing amount more than 0 part by weight and not more than 6.5 parts by weight for the molecular sieve with a pore diameter not less than 4.7 Å and not more than 5.3 Å; and a mixing amount more than 0 part by weight and not more than 7.0 parts by weight for the molecular sieve with a pore diameter not less than 10 Å and not more than 15 Å.
