A MSE-type zeolite which has a Si/Al ratio of 5 or more, is a proton-type zeolite, and is obtained by transforming a raw material MSE-type zeolite synthesized without using a structure directing agent into an ammonium-type zeolite through ion exchange, then, exposing the MSE-type zeolite to water vapor, and subjecting the exposed MES-type zeolite to an acid treatment.

Provided is a beta-type zeolite which has a high catalytic activity and is not easily deactivated. The beta-type zeolite of the invention has a substantially octahedral shape, has a Si/Al ratio of 5 or more, and is a proton-type zeolite. The Si/Al ratio is preferably 40 or more. This beta-type zeolite is preferably obtained by transforming a raw material beta-type zeolite synthesized without using a structure directing agent into an ammonium-type zeolite through ion exchange, then, exposing the beta-type zeolite to water vapor, and subjecting the exposed beta-type zeolite to an acid treatment.
