The object of the present invention is to provide a useful composition capable of suppressing cellular fibrousing. A pulse voltage is applied to the members to pass electric current therethrough, and the joint portion is heated by resistance heating generated at the bonding interface and in the bulk of the members to cause diffusion bonding and thereby to join the members to each other. The first and second layers are contacted to each other. The listing performance data provides sellers who have items listed for sale an insight as to how their item listings are performing in comparison to other item listings. The auxiliary box-shaped enclosure defines an auxiliary space isolated from the storage space with a deadening wall member.
