Battery package and battery module

A battery package:

• that accommodates a battery comprising upper and lower electrodes and at least one protrusion,
• the battery package comprising:
• an insulating substrate comprising a first surface, a second surface located on a side opposite to the first surface, and a first recessed portion that opens to the first surface and is configured to accommodate the battery;
• a first external electrode located on the second surface;
• a second external electrode located on the second surface;
• a first electrode located on a bottom surface of the first recessed portion and electrically connected to the battery and the first external electrode;
• a second electrode electrically connected to the battery and the second external electrode;
• an elastic member disposed on the first electrode and configured to electrically connect the battery and the first electrode;
• and
• a restriction portion configured to come into contact with the at least one protrusion to restrict the battery from moving in a direction away from the bottom surface of the first recessed portion due to an elastic force of the elastic member.
