An object of the present invention is to provide an elastic structure that has straightly extended ridges with excellent appearance, air permeability, and fluffy feel. The object can be attained by an elastic structure in which a first sheet material (12S) and a second sheet material (12H) are joined together to form sheet joined sections (70) by an adhesive (71) applied intermittently in an extending direction and continuously in a direction intersecting with the extending direction, resilient and elastic members (15 and 16) are fixed by the adhesive (71) to at least one of the first sheet material (12S) and the second sheet material (12H) at intersections with the sheet joined sections (70), and when the first sheet material (12S) and the second sheet material (12H) are contracted with contraction of the resilient and elastic members (15 and 16), portions of the first sheet material (12S) and the second sheet material (12H) positioned between the sheet joined sections (70) are swelled in mutually opposite directions to form ridges (80), and the sheet joined sections (70) have a width (70w) of 0.5 to 4 mm in the extending direction and spacing (70d) between the adjacent sheet joined sections (70) is 4 to 8 mm. |
