Abstract
There is provided a capacitor including: a main body in which a dielectric layer made of thermosetting resin and an electrode layer made of metal are laminated or wound; and an external electrode to which at least part of the main body is connected. The capacitor includes a metallikon region that is made of aluminum or an alloy containing aluminum, and a void ratio VR of at least a boundary region of the metallikon region that contacts the dielectric layer made of thermosetting resin and the electrode layer made of metal satisfies the following condition: 0<VR≤11%.

A method of manufacturing a capacitor comprising:
- manufacturing a main body in which a dielectric layer made of thermosetting resin and an electrode layer made of metal are laminated or wound;
- and
- forming an external electrode connected to at least a part of the main body,
- wherein forming the external electrode includes forming a metallikon region by spraying aluminum or an alloy containing aluminum so as to contact the main body, and
- forming the metallikon region includes keeping a temperature of at least a boundary region that contacts the dielectric layer made of thermosetting resin and the electrode layer made of metal at at least 150° C.
A method of manufacturing a capacitor comprising:
- manufacturing a main body in which a dielectric layer made of thermosetting resin and an electrode layer made of metal are laminated or wound;
