Abstract:
A capacitor 1 comprises: a capacitor element 10 including an element body 11 and an external electrode 12a (12b) provided on an end surface of the element body 11; a lead-out terminal 20a (20b) electrically connected to the external electrode 12a (12b); a metal case 30 inside of which the capacitor element 10 is accommodated so that the lead-out terminal 20a (20b) protrudes toward the exterior; an insulating member 40 that is accommodated in the interior of the metal case 30 and positions the capacitor element 10 so that the lead-out terminal 20a (20b) and the metal case 30 are not in contact; and a filler resin 50 with which the interior of the metal case 30 is filled so as to embed the capacitor element 10. A protrusion 35 protruding toward the capacitor element 10 is provided to the inner surface of the metal case 30 at a position at which the insulating member 40 is not present, and the shortest distance between the capacitor element 10 and the protrusion 35 is smaller than the shortest distance between the lead-out terminal 20a (20b) and the metal case 30.
