Abstract: Because it is possible to cool down a column member at a higher speed than natural cooling, throughput can be improved further. Especially, when the tubular body M42 and the column part M43 are made of different metals and the column part M43 is pressed into the tubular body M42, a distortion will occur in the column member M42 and M43 and the top board M41 fixed to the column member M42 and M43 due to the difference in thermal expansion coefficients between them, but the cooling paths P1 and P2 can absorb a distortion caused by the difference in thermal expansion coefficients of these metals. In particular, when the top board M41 is used as a mold for resin molding, it is possible to perform resin molding precisely because distortion caused by the difference in thermal expansion coefficients does not easily occur.
