Claims (7)

A solid electrolytic capacitor comprising: a capacitor element including an element body and an anode wire protruding therefrom; a cathode mounting terminal; and an anode mounting terminal conductively connected to the anode wire via a girder member,
The girder member is formed with a wall extending in a direction intersecting with the axis of the anode wire on the element body side of the joint between the girder member and the anode wire. The joint portion between the girder member and the anode wire is formed by laser welding, and the wall portion is not melted when the joint portion between the girder member and the anode wire is formed by laser welding. A solid electrolytic capacitor formed by the portion of the girder member remaining in the solid electrolytic capacitor. 2. The package according to claim 1, further comprising a resin package encasing said capacitor element, said girder member, said cathode mounting terminal and said anode mounting terminal while partially exposing said cathode mounting terminal and said anode mounting terminal. Solid electrolytic capacitor. The resin package has a first outer surface exposing a part of each of the cathode mounting terminal and the anode mounting terminal in a flush manner, and a second outer surface opposite to the first outer surface and parallel to the first outer surface. 3. The solid electrolytic capacitor of claim 2, wherein said anode wire extends parallel to said first outer surface and said second outer surface. The wall portion extends toward the second outer surface of the resin package, and the tip of the wall portion is positioned closer to the second outer surface than the joint portion between the beam member and the anode wire. 4. The solid electrolytic capacitor of claim 3, wherein the solid electrolytic capacitor is The anode wire is joined to the girder member in a state of being seated in a groove provided in the girder member, and the wall portion is closer to the element main body than the joining portion between the girder member and the anode wire. 5. The solid electrolytic capacitor according to claim 4, wherein one or both sides of said anode wire extend toward said second outer surface of said resin package. 6. The solid electrolytic capacitor according to claim 5, wherein said concave groove is V-shaped. 6. The solid electrolytic capacitor according to claim 5, wherein said concave groove is U-shaped.
