Package and method for manufacturing package

1. A package in which a power distribution member comprising a plurality of conductive wires is sealed in a packaging bag,

wherein an oxygen concentration in the packaging bag is lower than an oxygen concentration in an atmosphere,

wherein a plurality of the power distribution members and a tray holding the plurality of the power distribution members are sealed together in the packaging bag, wherein the tray comprises an outer frame and a partition wall dividing an inside of the outer frame into a plurality of housing chambers, and wherein the power distribution member is held in each of the plurality of housing chambers, and

wherein a plurality of the trays are stacked in the packaging bag, wherein the power distribution member comprises a resin holder integrally holding the plurality of conductive wires, and wherein the holder is sandwiched and held between a pair of the stacked trays.

2. The package according to claim 1 , wherein air pressure in the packaging bag is lower than an atmospheric pressure.

3. The package according to claim 1 , wherein the packaging bag is filled with an inert gas.

4. The package according to claim 1 , wherein the plurality of conductive wires are not in contact with the tray.

5. The package according to claim 1 , wherein each of the plurality of the trays is open on one side in a stacking direction, and wherein the power distribution members are not held in one of the plurality of the trays that is located at an end on the opening side.

6. A method for manufacturing the package according to claim 1 , the method comprising: holding the plurality of the power distribution members so as to be held in the trays; housing the trays holding the power distribution members in the packaging bag; reducing an amount of oxygen in the packaging bag; and hermetically closing an opening of the packaging bag.
