PROBLEM TO BE SOLVED: To easily separate a bubble sheet from an envelope body for separation disposal. SOLUTION: The envelope comprises an envelope body 1 made of a paper sheet wherein two laminated bubble sheets 4 and 5 formed by using a synthetic resin sheet as a material with air sealed in cells are sandwiched between a front sheet 2 and a rear sheet 3 and a three-side sealed portion comprising three peripheral sides except one of ends to serve as an entrance of contents is thermally welded. An end of one of the bubble sheets 4 overlying on an internal surface of the front sheet 2 of the envelope body 1 is glued and fixed to the internal surface of the front sheet 2 via an adhesive on the remaining one side other than the three sealed sides. In addition, an end of the other bubble sheet 5 overlying on an internal surface of the rear sheet 3 of the envelope body 1 is glued and fixed to the internal surface of the rear sheet 3 via an adhesive.
