To provide a heat shield that can measure temperature to evaluate the temperature distribution of a cathode during heating.SOLUTION: A heat shield 10 includes a cylindrical portion 11 that surrounds the outer periphery of a cathode 20 that extends in the axial direction, extends in the axial direction, and has heat insulating properties, and a slit 13A is formed in a region R of the circumferential surface of the cylindrical portion 11 that overlaps with the cathode in the axial direction, and the slit 13A penetrates the cylindrical portion 11 toward the cathode 20 and extends in a predetermined direction.SELECTED DRAWING: Figure 1 【課題】加熱時のカソードの温度分布を評価するための温度計測が可能なヒートシールドを提供する。【解決手段】ヒートシールド１０は、軸方向に延伸するカソード２０の外周を囲むと共に軸方向に延伸し、断熱性を有する円筒部１１を備え、円筒部１１の周面のうち、軸方向においてカソードと重なる領域Ｒにスリット１３Ａが形成され、スリット１３Ａは、カソード２０に向けて円筒部１１を貫通すると共に所定の方向に延伸している。【選択図】図１
