In FIG. 1, a plurality of hot-blade holders 1, 1 made of a refractory material such as ceramics are connected to a strip-shaped hot-blade main body 2 made of a nickel-chromium alloy or the like by bolts 3, 3. In the vicinity of the connecting portion of the band-shaped hot blade main body 2 with the hot blade holders 1 and 1 (FIG. 1)
(Left and right sides in FIG. 2), cuts 2A and 2A are provided from the upper part to a height position of half the height of the hot blade main body 2 in order to reduce the cross-sectional area of the hot blade main body 2.

Therefore, the electric resistance in the vicinity of the point A of the hot blade main body 2 increases, and the temperature rises. That is, the hot blade holder-1, 1
In the vicinity of the point A, the heat corresponding to the heat taken away is supplied, and the temperature of the hot blade main body 2 becomes substantially uniform throughout.
