Problems solved by technology

However, since the lower end of the belt portion 163 is not directly connected to the terminal forming portion 161 at a position perpendicular to the belt portion 163, the belt portion 163 does not have sufficient strength to withstand the force applied during resistance welding. I'm afraid it will bend due to the force

Abstract

The present invention provides a solid electrolytic capacitor and a manufacturing method thereof. The solid electrolytic capacitor has: a capacitor element with an anode lead protruding forward and a cathode layer formed on the surface; an encapsulation resin covering the capacitor element; An anode terminal and a cathode terminal on the exposed anode terminal surface and the cathode terminal surface; the anode terminal is electrically connected to the above-mentioned anode wire, and the cathode terminal is electrically connected to the above-mentioned cathode layer. Here, the anode terminal is formed of a single metal plate, and has: a terminal portion forming the surface of the anode terminal; a folded portion folded back at a side edge of the terminal portion and overlapping the upper surface of the terminal portion; The front end or rear end edge of the front end is vertically bent to the upper surface of the terminal portion; the front end of the anode lead is electrically connected to the front end of the upright portion.

Description

[0001] Japanese Patent Application No. 2008-277039, which is the basis of the priority claim of this patent application, is incorporated in the disclosure by reference. technical field [0002] The present invention relates to a solid electrolytic capacitor and a method of manufacturing the same. Background technique [0003] like Figure 12 As shown, the existing solid electrolytic capacitor has: a capacitor element 101 in which an anode wire (lead) 112 protrudes forward and a cathode layer 115 is formed on the surface; an encapsulation resin 102 covering the capacitor element 101; The anode terminal 103 and the cathode terminal 104 of the anode terminal surface 103a and the cathode terminal surface 104a exposed on the lower surface 102a. Furthermore, a connection member 105 having a predetermined height is connected to the upper surface of the anode terminal 103 , and a front end portion 112 a of the anode lead 112 is connected to the upper end of the connection member 105...
