Abstract
An all solid battery includes a solid electrolyte layer, a first electrode structure that has a structure in which a first electric collector layer of which a main component is a conductive material is sandwiched by two first electrode layers including an active material, and a second electrode structure that has a structure in which a second electric collector layer of which a main component is a conductive material is sandwiched by two second electrode layers including an active material. Roughness of interfaces between the first electric collector layer and the two first electrode layers and/or roughness of interfaces between the second electric collector layer and the two second electrode layers is larger than roughness of interfaces between the solid electrolyte layer, and the first electrode layer and the second electrode layer sandwiching the solid electrolyte layer.
