Film capacitor and method for manufacturing the same

A method for manufacturing a film capacitor, comprising the steps of:

• preparing a capacitor element having (a) a multilayer structure made of stacked dielectric films or a wound dielectric film, each dielectric film having a metallic layer formed on its surface, and (b) a pair of outer electrodes electrically connected to the metallic layer;
• and
• providing at least facets of the multilayer structure with a coating material so as to form a coating layer, the coating material containing at least one polysiloxane, at least one organometallic compound or a combination of the polysiloxane and the organometallic compound, the organometallic compound being selected from the group consisting of organoaluminum compounds, organosilicon compounds, organotin compounds and organotitanium compounds;
• and
• wherein the organometallic compound has at least one functional group attached to the metallic atom of the organometallic compound, the functional group being reactive to inorganic or organic materials and represented by the formula -OR, R being selected from the group consisting of hydrogen, hydrocarbyl, oxygen-containing hydrocarbyl, nitrogen-containing hydrocarbyl and oxygen- and nitrogen-containing hydrocarbyl.
