THIN FILM FOR SOLID-STATE BATTERY

An object of the present disclosure is to provide a thin film for a solid-state battery that is, due to low residual solvent content, less likely to adversely affect the performance of a solid-state battery and can be manufactured by a roll-to-roll continuous coating method. The present disclosure provides a thin film for a solid-state battery including solid electrolyte particles and crystalline fluororesin and binding the solid electrolyte particles together, in which at least part of the crystalline fluororesin has a fibrous shape, and the content of volatile components measured by a gas analysis means is 10 ppm by mass or less.
