Solid-state battery and method of manufacturing solid-state battery

A method of manufacturing a solid-state battery in which an electrode body and a heat dissipating material are accommodated in an exterior body, the method comprising:

• a step of accommodating the electrode body and the heat dissipating material in the exterior body such that the heat dissipating material contacts both the electrode body and the exterior body;
• and
• a step of compressing the heat dissipating material by pressing the electrode body in a layering axial direction of the electrode body and the heat dissipating material,
• wherein the heat dissipating material includes a material satisfying the following condition 2:
• condition 2:
• in a solid-state battery in which the heat dissipating material is accommodated between the electrode body and the exterior body, given that, in an environment of 25° C. and at a current value of 0.5C, one cycle is charging from a charge level of 0% to 100% and discharging from a charge level of 100% to 0%, when, after a cycling test in which the cycle is repeated 200 times, the solid-state battery is charged to a charge level of 100% and thereafter discharged to a charge level of 0%, the heat dissipating material contacts both the electrode body and the exterior body.
