1. A shaped catalyst of a complex metal oxide having molybdenum as an essential ingredient, which is a shaped catalyst used in production of butadiene by a gas-phase contact oxidative dehydrogenation reaction of n-butene in the presence of molecular oxygen, wherein pore volume of macropores of the shaped catalyst is 80% or more based on a total pore volume, wherein the shaped catalyst is a spherical coat-shaped catalyst in which the complex metal oxide is supported on an inert spherical support.
