    Abstract: PROBLEM TO BE SOLVED: To provide a lithium-ion capacitor that is industrially advantageously produced and achieves high-energy density, high power, low resistance, and high reliability. SOLUTION: The lithium-ion capacitor is configured as follows. A positive electrode and a negative electrode include a current-collecting material having through-holes, respectively. The positive electrode includes a material capable of reversibly carrying lithium-ions and/or anions as a positive-electrode active material with the material bound by a binder. The negative electrode includes a material capable of reversibly carrying lithium-ions as a negative-electrode active material. Lithium-ions are electrochemically carried by the positive electrode and/or the negative electrode. The binder is a particulate binder having a particle size of 0.1-0.4 μm and includes a composition comprising 5-20 mass% of a fluorine-containing polymer and a polymer that has a structural unit derived from CH 2 =CR 1 COOR 2 (R 1 represents a hydrogen atom or a methyl group and R 2 represents a 1-18C alkyl group or a 1-18C cycloalkyl group).
