The first and second sheets do not include an angled portion having an angle of about 90° or less between a joint and a support nearest to the joint. The expression 0.02≤b/a≤0.3 is satisfied, where a is a distance from an outer edge of the outermost support to an inner edge of the joint between the first and second sheets, and b is a distance between the first and second sheets at the outer edge of the outermost support.
