1. A beta zeolite satisfying formula (1) below in a range in which Q is less than 0.4011 nm,
P>76.79Q−29.514  (1),
wherein, P represents an A/B 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.
