    摘要： A joined structure (10) is provided with a laminate sheet (12A), a laminate sheet (12B), an adhesive (14) that joins the laminate sheet (12A) and the laminate sheet (12b), and an optical fiber (16) that is sandwiched between the laminate sheet (12A) and the laminate sheet (12B). As a result of the cross-sectional shape of the optical fiber (16) changing to an elliptical shape only when pressure is applied to the optical fiber (16) from a predetermined direction, birefringence that changes to a shape having a plurality of peaks (2, for example) occurs in the optical spectrum. The optical fiber (16) can be used as a sensor for detecting the joined state of the laminate layer (12A) and the laminate layer (12B) using the birefringence. As a result, it is possible to determine whether the members of the joined structure (10) are suitable joined.
