PURPOSE: To provide a thin and soft battery having a high energy density by forming a facing body for receiving a generating element from a single layer film of carbon film or a multilayer film containing carbon film.

CONSTITUTION: A thin type battery is formed of a negative electrode sheet 1 consisting of metal Li; a mix sheet 2 mainly containing MnO2; an electrolyte layer 3 consisting of a polypropylene nonwoven fabric impregnated with a nonaqueous solvent electrolyte obtained by dissolving lithium perchlorate to a mixed solution of propylene carbonate with dimethoxyethane; a frame-like sealing material 5 consisting of modified propylene; and a facing body used also as a positive electrode collector. Facing bodies 6, 7 are formed of single layer films of carbon film or multilayer films containing carbon film.
