Provided is a beta zeolite satisfying P>76.79Q−29.514 in a range in which Q is less than 0.4011 nm, wherein, P represents an AB value that is an intensity ratio of A to B, A represents a diffraction intensity of a main peak of the beta zeolite observed by X-ray diffraction measurement, B represents a diffraction intensity of the (116) plane of α-alumina obtained by X-ray diffraction measurement under the same conditions as those for the X-ray diffraction measurement on the beta zeolite, the α-alumina being the standard substance 674a distributed by the American National Institute of Standards and Technology, and Q represents a lattice interplanar spacing of the main peak of the beta zeolite observed by X-ray diffraction measurement. It is preferable that the formula (1) above is satisfied in a range in which Q is from 0.3940 to 0.4000 nm.
