The top side of the case (1) is composed of a fused part (1d) to be fused with the cover sheet. A fusion part (SP) for the whole circumference to be fused on the whole circumference of the opening part (1b) and an outer fusion part (OP) whose is at least partially fused to the outer part of the cover sheet are formed between the cover sheet and the fused part (1d) of the case (1).
