Abstract
There is provided a capacitor (1) including a main body (10), in which a plurality of dielectric layers (13) and a plurality of electrode layers (11) are alternatively laminated, and an external electrode (20) that is connected to at least part of the main body. Before forming an external electrode by metal spraying (metallikon) on the main body, at least part of a connection surface (30) where the metal spraying is performed is scanned with a laser beam (51) so that scanning marks (55) composed of concave-convex structures (35) are formed by the laser beam on at least part of the connection surface.
Claims12
A method of manufacturing a capacitor including a main body in which a plurality of dielectric layers and a plurality of electrode layers are alternately laminated, and an external electrode that is connected to at least part of the main body,
- the method comprising, scanning with a laser beam, before the external electrode is formed by metal spraying on the main body, at least part of a connection surface of the main body, which is to be subjected to the metal spraying and at which ends of the plurality of dielectric layers and ends of the plurality of electrode layers are exposed.
A capacitor comprising a main body, in which a plurality of dielectric layers and a plurality of electrode layers are alternately laminated, and an external electrode that is connected to at least part of the main body,
- the capacitor further comprising scanning marks produced by a laser beam on at least part of a connection surface of the main body where the external electrode is formed by metal spraying.
A capacitor comprising a main body, in which a plurality of dielectric layers and a plurality of electrode layers are alternately laminated, and an external electrode that is connected to at least part of the main body,
- the capacitor further comprising concave-convex structures, where at least part of ends of the plurality of electrode layers are recessed with respect to at least part of ends of the plurality of dielectric layers, on at least part of a connection surface where the external electrode is formed by metal spraying.
