Shaped bodies comprising a zeolite having an oxygen 8-membered ring structure, and at least any of a silica binder and a zirconia binder, the shaped bodies being such that the ratio of the cumulative pore volume of pores having a size of 10 nm or more and 100 nm or less to the cumulative pore volume of pores having a size of 5 nm or more and 300 nm or less is 25 vol % or more and 70 vol % or less, and the shaped bodies satisfy (1) or (2) below:
- (1) the average aspect ratio is 1.55 or less, and
- the particle size D50 is 200 μm or more and 600 μm or less;
- (2) the average aspect ratio is greater than 1.55.
