摘要

PURPOSE: A producing method of a battery having a thin film shape, the battery, and a vehicle and an electronic device including thereof are provided to install a solid electrolyte layer in between active material layers. CONSTITUTION: A producing method of a battery having a thin film shape comprises the following steps: producing a convex unit(121) protruded from the flat surface of a substrate using a first coating liquid containing a first active material; and coating a second coating liquid containing a solid electrolyte material on the surface of the substrate with the convex unit, for producing an electrolyte layer(13) covering the exposed surface(11a) of the substrate and the surface of the convex unit.
