Abstract: Conductive fins (107) are welded to the opposite sides of a band-like member (105a) with some of opposite end edges of the member left exposed to the outside to form a unit (105c). This unit (105c) is welded to a trunk body (101) from the outside at conductive fins (107). Next, a band-like member (105b) is allowed to span between adjacent band-like members (105a, 105a) and they are welded together from the outside. Welding permitted all from the outside eliminates the need of welding in a small, long space and facilitates a cask assembling work.
