Summary: | To suppress a leakage current and a short circuit.SOLUTION: A manufacturing method of an electrolytic capacitor pellet disclosed herein includes a filling step of filling a compression space 55 with a powder 41 containing a valve metal, a first compression step of compressing the powder 41 in the first direction D1 by narrowing the compression space 55 in the first direction D1, and a second compression step of compressing the powder 41 in the second direction D2 by narrowing the compression space 55 in the second direction D2 intersecting the first direction D1 after the first compression step.SELECTED DRAWING: Figure 2
【課題】漏れ電流やショート不良を抑制する。【解決手段】開示される電解コンデンサ用ペレットの製造方法は、圧縮用空間55に弁金属を含む粉体41を充填する充填工程と、圧縮用空間55を第1方向D1に狭めることで粉体41を第1方向D1に圧縮する第1圧縮工程と、第1圧縮工程の後、圧縮用空間55を第1方向D1と交差する第2方向D2に狭めることで粉体41を第2方向D2に圧縮する第2圧縮工程と、を備える。【選択図】図2 |
