Abstract
Provided is a susceptor capable of achieving improved thermal uniformity while suppressing reduction in its temperature increase rate and heat utilization efficiency. A susceptor includes a plate-shaped first member including a wafer placement surface on which to place a wafer, and a second member supporting the first member and laid on the first member in the direction perpendicular to the wafer placement surface. The thermal conductivity of the first member is higher than the thermal conductivity of the second member.
