PROBLEM TO BE SOLVED: To provide an air filter for high temperature and a manufacturing method of the same which can exhibit a filtration function without breakage and disassembly of each component even when exposed to a high temperature.SOLUTION: An air filter 1 for high temperature includes a filter pack 2 structured of a filter medium 4 and a separator, and a frame body 3 for housing the filter pack 2. A non-thermoplastic high-viscosity seal material 7 and a non-thermoplastic low-viscosity seal material 8 are respectively arranged between a lower end part and an upper end part of the filter pack 2 and an inner surface of the frame body 3. The low-viscosity seal material 8 is overlapped with a surface of the high-viscosity seal material 7 on a filter pack 2 side. Viscosity of the low-viscosity seal material is less than 100 Pa S. Viscosity of the high-viscosity seal material is 100-2000 Pa S.SELECTED DRAWING: Figure 3 【課題】高温にさらされても各部材の破損や分解を生じることなく、ろ過機能を発揮し得る高温用エアフィルタとその製造方法の提供。【解決手段】フィルタろ材４とセパレータとから構成されたフィルタパック２と、フィルタパック２を収容する枠体３とを有している高温用エアフィルタ１。フィルタパック２の下端部及び上端部と枠体３の内面との間には、非熱可塑性の高粘度シール材７及び非熱可塑性の低粘度シール材８がそれぞれ配置されており、低粘度シール材８は、高粘度シール材７のフィルタパック２側の面に重ねて形成されている高温用エアフィルタ１。前記低粘度シール材の粘度は１００Ｐａ・Ｓ未満であり、前記高粘度シール材の粘度は１００〜２０００Ｐａ・Ｓである、高温用エアフィルタ。【選択図】図３
