Abstract

Provided is a catalyst for manufacturing an unsaturated aldehyde and/or an unsaturated carboxylic acid, which is prepared by a method in which a molybdenum component raw material is composed of only an ammonium molybdate, the weight of water for dissolution is 8.5 times or less relative to the weight of molybdenum contained in the ammonium molybdate; and a bismuth component raw material is composed of only bismuth nitrate, the weight of a nitric acid aqueous solution for dissolution is 2.3 times or more relative to the weight of bismuth contained in the bismuth nitrate, and a nitric acid concentration in the nitric acid aqueous solution for dissolving the bismuth nitrate is 10% by weight or more.
