Claim:
1. A temperature adjusting apparatus of a mask substrate used in a mask drawing apparatus drawing a desired pattern by irradiating a charged particle beam to a mask substrate after a temperature of the mask substrate is adjusted in advance, the temperature adjusting apparatus comprising: a supporting member supporting the mask substrate; and first and second temperature adjusting plates facing each other with sandwiching the supporting member, the plates having a plurality of first and second regions respectively, and each temperatures of the first and second regions being capable to be independently adjusted, wherein a first distance from the first temperature adjusting plate to the mask substrate is approximately equal to a second distance from the second temperature adjusting plate to the mask substrate, and wherein the first regions in the first temperature adjusting plate include at least one region which temperature is different from those of other regions among the first regions, the second regions in the second temperature adjusting plate include at least one region which temperature is different from those of other regions among the second regions.
