Document Type and Number:
Japanese Patent JP7029670
Kind Code:
B2
Abstract:
To improve fixing properties and connection reliability of an element.SOLUTION: An electrolytic capacitor 100 comprises an element 10, an anode lead frame 50, a cathode lead frame 60A, and an outer package 70. The cathode lead frame has an exposed region 61, a contact region 62, and an erected region 63. A first bent part 601 obtained by bending the cathode lead frame toward the element serves as a boundary between the exposed region and the erected region. A second bent part 602 obtained by bending the cathode lead frame, thus bent at the first bent part, in a direction along a principal surface of the element serves as a boundary between the erected region and the contact region. The contact region is divided into two or more regions. The second bent part has: a third bent part which is obtained by bending a portion of the contact region thus divided in a first direction; and a fourth bent part which is obtained by bending the rest of the contact region in a second direction opposite to the third bent part. The contact region has: a first contact part extending from the third bent part in the first direction; and a second contact part extending from the fourth bent part in the second direction.SELECTED DRAWING: Figure 1
