PROBLEM TO BE SOLVED: To obtain an envelope in which sections to be laminated of the envelope are appropriately stuck through a hot-melt type adhesive regardless of seasons, and an appropriate sticking force can be kept even when the climate passes through a large change in cases when the seasons change from winter to spring and summer, and from summer to fall and winter. SOLUTION: Opposed surfaces of laminated sections 6 facing to each other by lamination are linearly coated in side-by-side arrangement with a hot-melt type adhesive 8 for a low temperature region, and a hot-melt type adhesive 7 for a high temperature region which exhibiting its impact durability and creep durability in a temperature range partly overlapping the temperature range where this hot-melt type adhesive 8 exhibiting its impact durability and creep durability.
