1. A container for a tab lead comprising:
a main body part configured to contain a plurality of tab leads; and
a cover part configured to cover the main body part,
wherein each of the tab leads comprises a conductor, which is a foil having a rectangular main surface, and an insulating film configured to cover a portion of the conductor and protruded from both ends in a width direction of the conductor,
wherein the main body part has a pocket,
wherein the pocket has an inverted quadrangular pyramidal trapezoid shape having a bottom surface and four side surfaces, in which an area of an opening at an upper end of the pocket is larger than an area of the bottom surface,
wherein a width of the bottom surface coincides with a width of the conductor of the tab lead in direction and length,
wherein the four side surfaces comprise a left side surface and a right side surface intersecting a straight line along a width direction of the bottom surface, and a front side surface and a rear side surface parallel to the straight line,
wherein the left side surface and the right side surface are not in contact with the insulating film of each of the tab leads in a state in which the plurality of tab leads are contained in the pocket,
wherein the front side surface is in contact with the insulating film of the tab lead closest to the front side surface in the state,
wherein the rear side surface is in contact with the insulating film of the tab lead closest to the rear side surface in the state,
wherein the left side surface and the right side surface each have a trapezoid where a bottom side is shorter than an upper side and all interior angles of the trapezoid formed by the bottom side and sides are obtuse angles, and
wherein the pocket is configured such that a volume of a region occupied by portions, which are below an upper end of the insulating films, of the plurality of tab leads in a state in which the plurality of tab leads are contained in the pocket is included within a range of 70% to 90% of a volume of the pocket.
