摘要：An object of the present invention is to provide a catalyst ensuring that in the
case of causing gas-phase catalytic oxidation of an unsaturated aldehyde and an oxygen-containing gas with use of the catalyst to produce a corresponding unsaturated
carboxylic acid, the pressure loss can be kept low and an unsaturated carboxylic acid canbe produced with high selectivity. The present invention relates to a ring-shaped orcolumnar catalyst, which is used at the time of producing a corresponding unsaturatedcarboxylic acid by causing gas-phase catalytic oxidation of an unsaturated aldehyde andan oxygen-containing gas, wherein the outer peripheral edge part is inclined relative tothe center line.
