A package structure that contains wet wipes formed of a laminated body of sheets (720, 710) impregnated with a predetermined chemical, inside a package main body, wherein: the package main body is provided with an opening portion through which the sheets are taken out; in the wet wipes, a convex region protruded toward a surface provided with the opening portion, is formed in a region including a region facing to the opening portion; in an unopened state in which the opening portion is unopened, a space is formed between the surface provided with the opening portion of the package main body and a region (800A, 800B) other than the convex region; characterised in that each of the sheets (720, 710) is folded back along a first folding line (1A, 1B), a second folding line (2A, 2B), a third folding line (3A, 3B) and a fourth folding line (4A, 4B); in a widthwise direction of each of the folded sheets, the first folding line and the second folding line are located between the third folding line and the fourth folding line; in each of the folded sheets, a rising region (PA, PB) is formed between the first folding line and the second folding line in the widthwise direction, the rising region having a four-layered structure in a lamination direction and other regions having a two-layered structure in the lamination direction; the rising region between the first folding line and the second folding line in the widthwise direction in a first sheet is not overlapped in the lamination direction with the rising region between the first folding line and the second folding line in the widthwise direction in an adjacent second sheet; regions are formed adjacent to the rising region between the first fold line and the second fold line in the widthwise direction of the first sheet; regions (RB, RC) are formed adjacent to the rising region between the first fold line and the second fold line in the widthwise direction of the adjacent second sheet; in the rising regions (PA, PB), the sheets (710, 720) adjacent to each other in the lamination direction are laminated in close contact with each other with a predetermined chemical intervened therebetween; and in the regions (RA, RB, RC) adjacent to the rising regions (PA, PB), a gap is formed between the sheets (710, 720) adjacent to each other in the lamination direction, the sheets in these regions not being laminated in close contact with each other with the predetermined chemical intervened therebetween. the package main body is provided with an opening portion through which the sheets are taken out; in the wet wipes, a convex region protruded toward a surface provided with the opening portion, is formed in a region including a region facing to the opening portion; in an unopened state in which the opening portion is unopened, a space is formed between the surface provided with the opening portion of the package main body and a region (800A, 800B) other than the convex region; characterised in that each of the sheets (720, 710) is folded back along a first folding line (1A, 1B), a second folding line (2A, 2B), a third folding line (3A, 3B) and a fourth folding line (4A, 4B); in a widthwise direction of each of the folded sheets, the first folding line and the second folding line are located between the third folding line and the fourth folding line; in each of the folded sheets, a rising region (PA, PB) is formed between the first folding line and the second folding line in the widthwise direction, the rising region having a four-layered structure in a lamination direction and other regions having a two-layered structure in the lamination direction; the rising region between the first folding line and the second folding line in the widthwise direction in a first sheet is not overlapped in the lamination direction with the rising region between the first folding line and the second folding line in the widthwise direction in an adjacent second sheet; regions are formed adjacent to the rising region between the first fold line and the second fold line in the widthwise direction of the first sheet; regions (RB, RC) are formed adjacent to the rising region between the first fold line and the second fold line in the widthwise direction of the adjacent second sheet; in the rising regions (PA, PB), the sheets (710, 720) adjacent to each other in the lamination direction are laminated in close contact with each other with a predetermined chemical intervened therebetween; and in the regions (RA, RB, RC) adjacent to the rising regions (PA, PB), a gap is formed between the sheets (710, 720) adjacent to each other in the lamination direction, the sheets in these regions not being laminated in close contact with each other with the predetermined chemical intervened therebetween.
