While adopting a thick positive electrode plate made of a sintered body, it is possible to significantly reduce the rate of increase in resistance during repeated use, and therefore, an all-solid lithium battery in which long-term reliability is greatly improved is provided. The all-solid lithium battery of the present invention comprises a self-supporting positive electrode plate having a thickness of 20 μm or more, made of a sintered body containing a plurality of crystal grains composed of a positive electrode active material, a lithium ion conductive material provided on the positive electrode plate A solid electrolyte layer comprising: a negative electrode layer containing lithium provided on the solid electrolyte layer; and a surface opposite to the solid electrolyte layer of the positive electrode plate in a non-adhesive state not including an adhesive And a positive electrode current collector that is a metal foil having a thickness of 5 μm to 30 μm. |
