Provided is a configuration of a solid state battery, which is capable of maintaining good electrical connection between a battery element and an electrode layer and is also capable of suppressing deterioration of the battery performance. A solid state battery (1) is provided with a battery element (10), a container member (20), a positive electrode terminal (110), a negative electrode terminal (120) and a collector member (111). The battery element (10) comprises a positive electrode layer (11), a solid electrolyte layer (13) and a negative electrode layer (12). The container member (20) houses the battery element (10). The positive electrode terminal (110) and the negative electrode terminal (120) are arranged on the outer surface of the container member (20). The container member (20) comprises a positive electrode connection part (112) and a negative electrode connection part (122) as conductor parts that are respectively connected to the positive electrode terminal (110) and the negative electrode terminal (120). The collector member (111) is arranged between the container member (20) and the positive electrode layer (11) and/or the negative electrode layer (12) so as to be connected to the conductor parts of the container member (20). The collector member (111) is elastic and contains a conductive substance. |
