CHIP TYPE SOLID ELECTROLYTIC CAPACITOR

PROBLEM TO BE SOLVED: To make a chip type solid electrolytic capacitor used for various electronic equipment compact. SOLUTION: The chip-type solid electrolytic capacitor comprises: an element stack of a plurality of flat plate type elements 1 provided with positive electrode portions 3 at both ends and also provided with a negative electrode portion 4 between the positive electrode portions 3; an positive conductive member 5 joined to the lowest stage of the element stack; an external package 6 covering the element stack in a state where respective end surfaces of the positive electrode portions 3 of the element stack are exposed on opposite end surfaces and the negative conductive member 5 is exposed on a bottom surface; a base electrode 7 connected to the positive electrode portions 3 of the element stack exposed on the opposite end surfaces of the external package 6; and an external electrode 9 formed on the base electrode 7, the base electrode 7 comprising a zinc layer formed by cold spraying. Consequently, the number of components and the assembly man-hour can be decreased to make the chip-type solid electrolytic capacitor low-cost and compact, and respective electrodes are led out by the shortest distances to reduce ESL.
