Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a window frame (2) which is realized by a relatively simple step in place of a conventional style filling hollow parts (4a-4f) with a heat insulation material or in addition thereto, and which has heat insulating properties improved reliably.SOLUTION: A low-radiation film (14) having emissivity lower than emissivity of an inner surface of a wall is arranged on at least a part of the inner surface of the wall, which defines hollow parts (4a-4f).SELECTED DRAWING: Figure 1 【課題】中空部（４ａ乃至４ｆ）に断熱材を充填する従来の様式に代えて或いはこれに加えて、比較的簡単な工程によって実現され断熱性が確実に増大せしめられた窓枠（２）を提供する。【解決手段】中空部（４ａ乃至４ｆ）を規定している壁内面の少なくとも一部に、壁内面の放射率よりも小さい放射率を有する低放射膜（１４）を配設する。【選択図】図１
