PROBLEM TO BE SOLVED: To provide a thermal insulation material capable of being easily and reliably fitted between frame members without processing a groove or the like, an attachment structure of the thermal insulation material, and a manufacturing method of the thermal insulation material.SOLUTION: A thermal insulation material 10 has plural foam members 11, 11 obtained by extruding and foaming a foaming material, which are integrally disposed so as to make each extrusion direction 13 into an identical direction. The thermal insulation material 10 has a cut face 12 in a direction perpendicular to the extrusion direction 13. The cut face 12 functions as an insulation face to prevent heat from passing therethrough.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】溝などの加工をしなくても枠体間へ簡易にかつしっかりと嵌め入れできる断熱材、その断熱材の取付構造およびその断熱材の製造方法を提供する。【解決手段】断熱材10は、発泡材料を押出発泡した複数の発泡体11、11、・・・が、押出方向13が同一方向となるように配されて一体化され、押出方向13に直交する方向に切断した切断面12を有しており、切断面12が熱通過に対する断熱面とされる。【選択図】図1
