Abstract: A solid electrolytic capacitor 1 includes a capacitor element 2 and a resin package 9 enclosing the capacitor element. The capacitor element includes a sintered body 3 of valve metal powder, an anode 4a provided by embedding an anode wire 4 in the sintered body, and a cathode 5 provided by forming a metal layer on the sintered body. A first lead member 6 in the form of a plate is connected to the anode wire 4. The end of the first lead member projects from a side surface 9a of the resin package 9 to provide an anode terminal T1. A second lead member 7 in the form of a plate is connected to the cathode 5. The end of the second lead member projects from a side surface 9b of the resin package 9 to provide a cathode terminal T2. By extending the first and the second lead members 6 and 7 generally horizontally at the substantially same height from the lower end of the resin package and making the portions projecting from the resin package 9 serve as the anode terminal T1 and the cathode terminal T2, the lead length between the anode 4a of the capacitor element 2 and the anode terminal T1 and the lead length between the cathode 5 and the cathode terminal T2 is made as short as possible, whereby ESL is reduced.

Abstract: A method is provided for making a solid electrolytic capacitor comprising a flattened porous body. According to this method, use is made of a pair of pressure blocks and a vertical movement block for engagement with the pair of pressure blocks. The pair of pressure blocks face each other and are horizontally movable. A space is formed between these two pressure blocks for loading powder made of a valve metal. The powder loaded in the space is compressed by the pair of pressure blocks to form a flattened porous body. The compression by the pair of pressure blocks is brought about by a downward motion of the vertical movement block held in engagement with the pair of pressure blocks.
