A capacitor includes a capacitor element, a case that houses the capacitor element and contains a resin, a metal plate insert molded in the case, and a filler resin filled in the case. The metal plate includes a main plate portion and a covered portion disposed along a perimeter of the main plate portion. The main plate portion has an outer surface exposed outwardly from an opening of the case. The covered portion has an outer surface covered by a peripheral portion of the case, the peripheral portion being disposed around the opening.

Capacitor

A film capacitor includes a capacitor element, a first bus bar and a second bus bar, a case, and a filling resin. The first bus bar has a first overlapping part, and the second bus bar has a second overlapping part. The first overlapping part and the second overlapping part overlap with each other via an insulating plate. The insulating plate has a first surface that faces the first overlapping part and a second surface that faces the second overlapping part, and has a first protrusion formed on the first surface and a second protrusion formed on the second surface, the second protrusion opposing the first protrusion. The first overlapping part has a first fitting hole into which the first protrusion is fitted, and the second overlapping part has a second fitting hole into which the second protrusion is fitted. The insulating plate has a through-hole that penetrates through the first protrusion and the second protrusion.

Film capacitor

First sheet-like substrate is arranged at a region surrounded by first terminals of male connector and first circuit substrate, and second sheet-like substrate is arranged at a region surrounded by second terminals of female connector and second circuit substrate, and male connector and female connector are fitted together so that a first passive element of first sheet-like substrate and a second passive element of second sheet-like substrate configure a filter circuit.

Electronic circuit connection structure and its manufacturing method

A capacitor ( ) using a flexible substrate ( ) includes a hole portion ( ) formed in a dielectric ( ) to connect an upper electrode ( ) to an external leader electrode ( ). At least part of the hole portion ( ) extends from its lower end to upper end at an inclination between 0.1 and 20&deg; with respect to a top surface of the external leader electrode ( ). Then, an upper end corner of an inclined wall surface of the upper electrode ( ), which inclines along the hole portion ( ) of the dielectric ( ), has a downward inclination between 0.1 and 20&deg;. A lower end corner of the inclined wall surface of the upper electrode ( ), which inclines along the hole portion of the dielectric ( ), has an upward inclination between 0.1 and 20&deg;. As a result, stress concentration on the corners of the upper electrode ( ) is drastically reduced to prevent the upper electrode ( ) from cracking.
