<p>PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor of low ESR, by suppressing infiltration of moisture, oxygen, and the like, in the air into the exterior resin.SOLUTION: The cathode layer and the cathode terminal 4 of a capacitor element 10 having the cathode layer on the surface of an anode body 1, consisting of a porous body of a valve action metal and from which an anode lead 2 is led out, are connected electrically, the anode lead 2 and an anode terminal 3 are connected electrically, a part of the capacitor element 10 and anode terminal 3 and a part of the cathode terminal 4 are coated with a first exterior resin 5, and at least a part of the anode terminal 3 and cathode terminal 4 not coated with the first exterior resin 5, and at least a part of the first exterior resin 5 is coated with a second exterior resin 30, at least one of the oxygen permeation and steam permeation of which is lower than that of the first exterior resin 5.</p> |
