Abstract
A roll-up type capacitor that includes a plurality of cylindrical parts arranged parallel to one another and which each are a rolled-up laminate; a first external electrode on respective first ends of the plurality of cylindrical parts; and a second external electrode on respective second ends of the plurality of cylindrical parts. When, prior to being rolled-up, a dimension of the laminate parallel to a rolling-up direction is a length L, and a dimension of the laminate perpendicular to laminating direction and the rolling-up direction is a width W, the roll-up type capacitor has two or more cylindrical parts when a ratio L/W is 4 or more; has three or more cylindrical parts when L/W is 3 to less than 4; has four or more cylindrical parts when L/W is 2 to less than 3; and has eight or more cylindrical parts when L/W is 1 to less than 2.
