Film capacitor, film, and metallized film

A film capacitor comprising:

• a wound body in which a dielectric film and a metal layer are wound, the dielectric film including a cured product of a first organic material having a hydroxy group and a second organic material that is an aromatic compound having an isocyanate group, the dielectric film including a first main surface and a second main surface opposed to each other in a thickness direction, the metal layer being disposed at least on the first main surface of the dielectric film,
• wherein the first main surface of the dielectric film includes a plurality of protrusions having the second organic material,
• a surface of the metal layer on an opposite side of the first main surface of the dielectric film includes a plurality of protruding parts coinciding with the plurality of the protrusions, and
• in an area range of 100 μm by 140 μm of the surface of the metal layer, the plurality of the protruding parts have an average diameter of 0.60 μm to 6.13 μm and an average height of 0.13 μm to 2.63 μm, and a number of the plurality of the protruding parts ranges from 50 to 450.

A metallized film comprising:

• a film including a cured product of a first organic material having a hydroxy group and a second organic material that is an aromatic compound having an isocyanate group, and including a first main surface and a second main surface opposed to each other in a thickness direction;
• and
• a metal layer disposed at least on the first main surface of the film,
• wherein the first main surface of the film includes a plurality of protrusions having the second organic material,
• a surface of the metal layer on an opposite side of the first main surface of the film includes a plurality of protruding parts coinciding with the plurality of the protrusions, and
• in an area range of 100 μm by 140 μm of the surface of the metal layer, the plurality of the protruding parts have an average diameter of 0.60 μm to 6.13 μm and an average height of 0.13 μm to 2.63 μm, and a number of the plurality of the protruding parts ranges from 50 to 450.
