図5に示されるように、裏側シート端部53bが表面被覆部51と封止層20との間に配置されており、かつ、遮蔽部70が裏面保護材40の裏面に設けられていてもよい。この例においても、表側延長部54が省略され、表側バリアシート50Aが表面被覆部51のみで構成されてもよい。また、この例では、表面保護材30のフランジ部32は、省略されていてもよい。
図6に示されるように、裏側バリアシート50Bから裏側張出部53が省略され、表側バリアシート50Aは、表側延長部54に代えて表側張出部55を有していてもよい。表側張出部55は、表面被覆部51の縁部から張り出しておりかつ表面保護材30から離間している。表側張出部55は、包囲端面S3を被覆した状態で裏側バリアシート50Bに接続されている。表側張出部55は、端面被覆部55aと、表側シート端部55bと、を有している。
図7に示されるように、表側シート端部55bは、裏面被覆部52と封止層20との間に配置されていてもよい。この場合、裏側延長部56が省略され、裏側バリアシート50Bが裏面被覆部52のみで構成されてもよい。この例では、表側バリアシート50Aと裏側バリアシート50Bとが表側接着層50Cを介して互いに接続されるため、第1変形例と同様に気密性が向上する。
図8に示されるように、表側シート端部55bが裏面被覆部52と封止層20との間に配置されており、かつ、遮蔽部70が裏面保護材40の裏面に設けられていてもよい。この場合においても、裏側延長部56が省略され、裏側バリアシート50Bが裏面被覆部52のみで構成されてもよい。また、この例では、表面保護材30のフランジ部32は、省略されていてもよい。
