  • pillars (pillars 4,304) that pass through the center 6 of the frame 2 and extend between the frames 2 are provided in the frame 2 having an opening. It is provided, and is provided from the center of the surrounding portion (centers 12, 312) to the end portion of the surrounding portion (center 12, 312) in the surrounding portion (surrounding portion 10,310) surrounded by the frame body 2 and the pillar portion (pillar portion 4,304). It has a common feature that it has a plurality of sub-pillars (sub-pillars 14, 15, 16, 17, 18) extending toward the frame 2 and the pillars). As a result, during firing, the temperature difference between the center of the surrounding portion and the end portion of the surrounding portion (difference in temperature followability) is alleviated, and the in-plane temperature distribution of the setter can be reduced.
