Generally, this type of solid electrolytic capacitor is
As shown in the figure, a metal wire having a valve action is attached in advance to a capacitor element A which is formed by press-forming metal powder having a valve action into a prismatic shape and sintering it, and an anode lead B.
A plate-shaped first external lead member C is welded to this anode lead B, and a plate-shaped second external lead member C is welded to the anode lead B.
Connect the external lead member D to the electrode lead layer E of the capacitor element A using a conductive adhesive,
And the entire circumferential surface of capacitor element A is covered with resin material F.
It is constructed by mold coating.

C,Dは陽極、陰極なる極性表示を何らかの方法
で行う必要がある。 By the way, in this capacitor, capacitor element A and anode lead B serve as an anode.
Since the electrode lead layer E functions as a cathode, the first and second external lead members C and D connected thereto need to be designated as an anode or a cathode by some method.
従つて、従来においては第1図に示すように、

によつて極性表示が行われている。 Therefore, in the past, as shown in Figure 1,
A notch-like irregularly shaped part G is formed on the upper surface end of the resin material F on the lead-out side of the first external lead member C, or a display symbol is stamped, and the external lead on the side where it is formed is formed. Polarity is indicated by using the member as an anode.
しかし乍ら、例えば第2図に示すように、プリ

反転させる必要が生ずるものの、設備が複雑化
し、かつ操作も煩雑化するという問題がある。 However, as shown in Figure 2, for example, when the capacitor is mounted on a printed board, etc.
If the irregularly shaped part G is reversed so that it is on the lower side, the irregularly shaped part G can be recognized, thereby making it impossible to determine the polarity. For this,
Although it is necessary to reverse the capacitor to its normal position by some means, there are problems in that the equipment becomes complicated and the operation becomes complicated.
それ故に、本案の目的は簡単な構成によつて反

る。 In the figure, 1 is a capacitor element (component body) made by press-forming metal powder with valve action into a prismatic shape and sintering it. A functional metal wire is installed as an anode lead 2. Incidentally, the capacitor element 1 can be formed into any suitable shape such as a columnar shape in addition to a prismatic shape, and the anode lead 2 can also be welded to the circumferential surface of the capacitor element 1 to lead out. An electrode lead layer 3 is formed on the circumferential surface of the capacitor element 1 via an oxide layer and a semiconductor layer. On the other hand, a plate-shaped first external lead member 4 is welded to the anode lead 2.
A plate-shaped second external lead member 5 is connected to the electrode lead layer 3 using a conductive adhesive 6. The entire circumferential surface of the capacitor element 1 is molded and covered with a resin material 7 so that a deformed portion 8 is formed at the end of the upper surface 7a. And, first,
The portions of the second external lead members 4 and 5 extending from the resin material 7 are bent along the side surface 7b and bottom surface 7c of the resin material 7, and are particularly formed at the leading end of the first external lead member 4.

きる。 According to this embodiment, the first external lead member 4
A wide portion 4a is formed at the leading end of the resin material 7.
Since it is bent so as to stand up along the side surface 7b of the lead member 4, even if it is turned upside down during mounting on a printed board, the first and second external lead members 4 will not bend as shown in FIG. , 5 are different in shape from each other, polarity can be easily and reliably determined.
