Summary:The present invention relates to an all-solid-state battery including: a positive electrode plate; a solid electrolyte layer disposed on one side of the positive electrode plate; a negative electrode plate disposed on one side of the solid electrolyte layer; and a buffer film disposed on one side of the negative electrode plate. The buffer film includes: a substrate; and a buffer layer formed by attaching first microparticles (MS1), which are formed on at least one surface of the substrate to provide restoring force, and second microparticles (MS2), which relieve stress, with a binder. 전고체 전지에 관한 것으로서, 이 전고체 전지는, 양극극판, 상기 양극극판의 일측에 배치되는 고체전해질층, 상기 고체전해질층의 일측에 배치되는 음극극판 및 상기 음극극판의 일측에 배치되는 완충필름을 포함하며, 상기 완충필름은 기재, 및 상기 기재의 적어도 일면에 형성되어 복원력을 제공하는 제1 미립자(MS1)와 응력을 완화하는 제2 미립자(MS2)를 바인더로 부착하여 형성되는 완충층을 포함한다.
