PROBLEM TO BE SOLVED: To provide an eaves soffit ventilation material which can increase ventilation efficiency without expanding a space between an exterior wall material and a fascia board, and which has excellent fire resistance efficiency.SOLUTION: In a ventilation material, a horizontal ventilation part 2 and a vertical ventilation part 6 are continuously provided in an inverted L-shape so that an L-shaped ventilation passage 17 can be formed. An opening end surface 3 of the horizontal ventilation part 2 is formed as an inclined plane by extending a bottom surface 4 forward. An exterior wall concealing plate 5 is provided in a hanging state in an intermediate part of the bottom surface 4. The vertical ventilation part 6 comprises an outside plate 7, a bottom surface plate 8 and an inside plate 9. The bottom surface plate 8 and the inside plate 9 are provided with a ventilation opening 10. The inside plate 9 is brought away from the exterior wall concealing plate 5, and a ventilation space 11 is secured therein.SELECTED DRAWING: Figure 1 【課題】外壁材と鼻隠しとの間の間隔を広げることなく、換気効率を向上させることが可能で、優れた耐火性能を有する軒天換気材を提供することを課題とする。【解決手段】水平通気部２と垂直通気部６とが倒Ｌ字型に連設されてＬ字型の通気路１７が形成される換気材であって、水平通気部２の開口端面３は底面４を先延ばしにして斜面に形成され、底面４の中間部に外壁隠蔽板５が垂設され、垂直通気部６は、外側板７と底面板８と内側板９とから成り、底面板８と内側板９に通気開口１０が設けられ、内側板９は外壁隠蔽板５から離隔されてそこに通気空間１１が確保される。【選択図】図１
