NOVELTY - The method involves electrostatically spraying active material and solid electrolyte toward to-be-coated material (4) i.e. aluminum foil, from different nozzles (1x-3x), while controlling assignment of electrolyte dispersion liquid i.e. sulfide type solid electrolyte, to the to-be coated material. Active material dispersion liquid and the electrolyte dispersion liquid are stirred during electrostatic spraying such that the active material is in dried condition at the time of attainment to a surface of the to-be-coated material. A grounded table (5) is moved along plane direction.    USE - Method for manufacturing a solid battery electrode layer for a solid battery i.e. lithium ion secondary battery, used in an information technology equipment i.e. mobile telephone, and for a vehicle e.g. electric vehicle and hybrid vehicle.    ADVANTAGE - The active material and the solid electrolyte are electrostatically sprayed toward the to-be-coated material from the different nozzles so as distribute positive electrode active material, solid electrolyte and electrically conductive auxiliary material in an uniform manner, thus uniformly distributing the positive electrode active material with desired compounding ratio, and hence improving productivity of a solid battery electrode layer and preventing fall of battery performance.    DETAILED DESCRIPTION - The active material dispersion liquid is positive electrode active material dispersion liquid and negative electrode active material dispersion liquid. The aluminum foil is an 18-micrometer-thick aluminum foil. The active material is lithium cobaltate and lithium nickelate. An INDEPENDENT CLAIM is also included for a manufacturing apparatus for a solid battery electrode body.
