Battery package, assembled battery, and battery device

A battery package comprising:

• a plurality of sets of one pair of conductor sheets facing each other,
• wherein
• the one pair of conductor sheets facing each other has a plurality of linear adhesive parts;
• the plurality of linear adhesive parts are formed apart from each other in a width direction orthogonal to a length direction;
• the one pair of conductor sheets facing each other form a plurality of cylindrical parts partitioned with the plurality of linear adhesive parts;
• a battery accommodating part is secured inside each of the plurality of cylindrical parts;
• the one pair of conductor sheets facing each other is continuously formed in a width direction over the plurality of cylindrical parts;
• each of the plurality of cylindrical parts is formed with intermediate parts between adjacent two of the plurality of linear adhesive parts of the one pair of conductor sheets facing each other;
• at least a part of each of the intermediate parts of the one pair of conductor sheets facing each other has a bending shape that is convexed outward;
• each of the one pair of conductor sheets facing each other is partially adhered to opposite one of the one pair of conductor sheets facing each other at the plurality of linear adhesive parts on its one surface, and is partially adhered to other set of one pair of conductor sheets facing each other at a plurality of adhesive parts on the other surface, wherein the plurality of linear adhesive parts on the one surface of the plurality of adhesive parts on the other surface are alternately arranged in a width direction;
• and
• a space is secured between one set of the plurality of sets of one pair of conductor sheets facing each other and the other set of one pair of conductor sheets facing each other, the two sets adjoining to each other in a thickness direction.
