Abstract
A capacitor element of a capacitor is connected to a lead terminal and is covered with a resin. The lead terminal is derived from a resin layer covering the capacitor element and includes an interval portion exposed from an outer face of the resin layer, a small-thickness portion, and a step portion that is a border portion between the interval portion and the small-thickness portion. The small-thickness portion is bent toward the step portion, is disposed on a side of the resin layer and is disposed to superpose the small-thickness portion on the step portion and to surround the interval portion.
Claims11
A capacitor comprising a capacitor element to which a lead terminal is connected and that is covered with a resin, wherein
- the lead terminal is derived from a resin layer covering the capacitor element, and comprises:
- an interval portion exposed from an outer face of the resin layer;
- a small-thickness portion;
- and
- a step portion that is a border portion between the interval portion and the small-thickness portion, and wherein
- the small-thickness portion is bent toward the step portion, is disposed on a side of the resin layer and is disposed to superpose the small-thickness portion on the step portion and to surround the interval portion.
A manufacturing method for a capacitor comprising a capacitor element to which a lead terminal is connected and that is covered with a resin, the manufacturing method comprising the steps of:
- deriving the lead terminal from a resin layer covering the capacitor element, and exposing an interval portion from an outer face of the resin layer;
- forming a small-thickness portion in the lead terminal to dispose a step portion between the interval portion and the small-thickness portion;
- and
- bending the lead terminal in the small-thickness portion toward the step portion and disposing the small-thickness portion to superpose the small-thickness portion on the step portion and to surround the interval portion.
