CAPACITOR, METHOD OF MANUFACTURING THEREOF AND PRINTED CIRCUIT BOARD HAVING THE CAPACITOR

摘要

A capacitor, a manufacturing method thereof, and a printed circuit board with the capacitor are provided to improve adhesion force between the capacitor and an insulation layer. A printed circuit board includes a first electrode layer, a second electrode layer, a dielectric layer(20), and an insulation layer. One surface of the second electrode layer is opposed to the first electrode layer. A protrusion(15) is formed on the other surface of the second electrode layer. The dielectric layer is interposed between the first electrode layer and the second electrode layer. The protrusion is made of the same material as the second electrode. The protrusion is formed in plural. The plurality of protrusions is arranged at a regular interval. The protrusion is formed through electrolyte plating. The insulation layer is stacked on the other surface of the second electrode layer.
