Disclosed are: a solid electrolyte battery having a solid electrolyte layer having a low resistivity; a vehicle having the solid electrolyte battery mounted therein; a battery-mounted apparatus; and a method for producing the solid electrolyte battery. The solid electrolyte battery (1) comprises: a positive electrode active material layer (21) which contains a positive electrode active material particle (22); a negative electrode active material layer (31) which contains a negative electrode active material particle (32); and a solid electrolyte layer (40) which is arranged between the positive electrode active material layer (21) and the negative electrode active material layer (31), wherein the solid electrolyte layer is free of any binder comprising a resin, contains a sulfide solid electrolyte (SE), is self-held through the binding force of the sulfide solid electrolyte, and has a thickness (40T) of 50 mu m or less and a surface area (40S) of 100 cm2 or more.
