| abstract | [PROBLEMS] To produce a corresponding unsaturated carboxylic acid by gas phase catalytic oxidation of an unsaturated aldehyde such as acrolein, to reduce pressure loss and maintain a high gas amount, thereby suppressing coking, Providing a catalyst capable of producing the corresponding unsaturated carboxylic acid in high yield. A ring-shaped catalyst having a straight body portion A and a cavity portion B, which is used when a unsaturated aldehyde is produced by vapor-phase catalytic oxidation to produce a corresponding unsaturated carboxylic acid, A catalyst in which the length 3 is shorter than the length 7 of the cavity, and at least one end is curved from the end of the straight body to the end C of the cavity.
