To provide a method of manufacturing a battery preventing a fault caused by peeling of a film of an alignment mark.
The method of manufacturing the battery with laminated films has a negative electrode active substance first arrangement process for arranging a negative electrode active substance first liquid film 111 on a negative electrode current collector sheet 110 to form a negative electrode active substance first liquid film pattern 111k; a negative electrode active substance second arrangement process for arranging a negative electrode active substance second liquid film 114; and a first solidifying process for solidifying the negative electrode active material first liquid film 111 and the negative electrode active substance second liquid film 114. The negative electrode active substance second arrangement process has a detecting process, a position computing process and an applying process. In the detecting process, a location of the negative electrode active substance first liquid film pattern 111k is detected. In the position computing process, a location of arranging the negative electrode active substance second liquid film 114 is computed using information on the location of the negative electrode active substance first liquid film pattern 111k. In the applying process, material of the negative electrode active substance second liquid film 114 is applied to the computed location.
