Zusammenfassung:	To provide an eaves soffit structure capable of improving fire resistance performance.SOLUTION: An eaves soffit structure 1 includes a ceiling joist 10 to which an eaves soffit material 30 is fixed, a lower heat insulating material 71 provided to cover the ceiling joist 10, and an upper heat insulating material 72 provided to cover the lower heat insulating material 71. The lower heat insulating material 71 includes an eaves-edge-side heat insulating material 71a disposed on the eaves-edge side and an eaves-base-side heat insulating material 71b. In addition, a plurality of ceiling joists 10 is provided, and the eaves-edge-side heat insulating material 71a and the eaves-base-side heat insulating material 71b are provided so as to cover different ceiling joists 10 (ceiling joist 10c and ceiling joist 10b).SELECTED DRAWING: Figure 1 【課題】耐火性能を向上させることができる軒天構造を提供する。【解決手段】軒天構造１は、軒天材３０が固定される野縁１０と、野縁１０を覆うように設けられた下側断熱材７１と、下側断熱材７１を覆うように設けられた上側断熱材７２と、を具備する。また、下側断熱材７１は、軒先側に配置される軒先側断熱材７１ａと、軒元側に配置される軒元側断熱材７１ｂと、を具備する。また、野縁１０は複数設けられ、軒先側断熱材７１ａ及び軒元側断熱材７１ｂそれぞれが異なる野縁１０（野縁１０ｃ、野縁１０ｂ）を覆うように設けられている。【選択図】図１
