Zusammenfassung:PROBLEM TO BE SOLVED: To provide a mask for charged particle beam exposure eliminating thermal deflection and displacement of a membrane due to heat storage during exposure without blocking formation of a fine mask pattern, and to provide a method of manufacturing the mask for charged particle beam exposure. SOLUTION: The mask for charged particle beam exposure includes a first wafer 4 and a second wafer 1 bonded to the first wafer 4. The second wafer 1 has a mask pattern 14 for transfer formed on a top side. The first wafer 4 has a mask pattern 44 formed on a top side, and an opening 45 of the mask pattern 44 is opposed to an opening 15 of the mask pattern 14 for transfer and has a size larger than the size of the opening 15 of the mask pattern 14 for transfer.
