PROBLEM TO BE SOLVED: To provide an envelope which is more easily opened than a conventional one.;SOLUTION: The envelope 1 includes a cover 103 provided to be connected to the enclosing port side 24 of a cover 10, and a flap 3 provided to be connected to the enclosing port side 25 of a backing sheet 11. The flap 3 includes a cut-to-open part 31 and a tab 336 in order from the side of the enclosing port side 25. The cut-to-open part 31 is formed to be wider toward the enclosing port side 25, and accommodated in the envelope 1 by being bent to the inside of the envelope 1. The tab 336 is pulled out to the outside of the envelope 1 from a pull-out opening 104 formed at the cover 103. By pulling the tab 336, the cut-to-open part 31 is pulled out from the inside of the envelope 1 while cutting the enclosing port side 25. Thus, the cut opening of the enclosing port 25 is extended to the width of the base 314 of the cut-to-open part 31, and the envelope 1 is opened.;COPYRIGHT: (C)2012,JPO&INPIT
