Abstract
A film capacitor that includes: a laminate including a first dielectric film, a second dielectric film, a first metal layer, and a second metal layer laminated in a laminate direction; a first external electrode on a first end surface of the laminate in a width direction perpendicular to the laminate direction and connected to the first metal layer; and a second external electrode on a second end surface of the laminate in the width direction, the first external electrode having first protrusions arranged in the laminate direction and protruding toward the second external electrode in the width direction, at least one of the first protrusions of the first external electrode having a first protrusion end with a width greater than a total thickness of the first dielectric film and the second dielectric film by two times or more.
