Zusammenfassung:To provide a structure with improved heat radiation properties.SOLUTION: A structure is heated to 700°C or more, and has a heat radiation unit that radiates heat of the structure. The heat radiation unit has, on its surface, a first uneven structure in which a plurality of first projections and a plurality of first recesses are alternately arranged. A peak wavelength of electromagnetic waves thermally radiated from the heat radiation unit is 3 μm or less. The distance between first projections adjacent to each other of the plurality of first projections, or the distance between first recesses adjacent to each other of the plurality of first recesses, is less than 1/2 of the peak wavelength.SELECTED DRAWING: Figure 2 【課題】 本発明の目的は、放熱性を向上させた構造体を提供することにある。【解決手段】 700℃以上に加熱される構造体であって、前記構造体の熱を放熱する放熱部を有し、前記放熱部の表面に、複数の第1凸部および複数の第1凹部が交互に配置された第1凹凸構造を有し、前記放熱部から熱放射される電磁波のピーク波長は、3μm以下であり、前記複数の第1凸部のうち、互いに隣接する第1凸部間の距離、または前記複数の第1凹部のうち、互いに隣接する第1凹部間の距離は、前記ピーク波長の1/2未満であることを特徴とする構造体。【選択図】 図2
