PROBLEM TO BE SOLVED: To provide a compact and thin capacitor which has high electrostatic capacitance and a high frequency characteristic. SOLUTION: This capacitor includes a cured body of polycarbodiimide represented by a specific formula as a dielectric. A diisocyanate residue of 10 mol% or more in polycarbodiimide is an aromatic diisocyanate residue, and the diisocyanate residue is at least one kind selected from a group composed of a tolylene diisocyanate residue, a 4,4'-diphenylmethane diisocyanate residue, and a naphthalene diisocyanate residue, and the capacitor is the one in which a monoisocyanate residue in the polycarbodiimide is an aromatic monoisocyanate residue. The aromatic monoisocyanate residue is a 1-naphthyl isocyanate residue. COPYRIGHT: (C)2005,JPO&NCIPI
