Provided is a catalyst for COS hydrolysis that can maintain a high COS conversion rate even after long use, and a method of producing the same. The catalyst for COS hydrolysis includes titanium dioxide and a barium compound supported on the titanium dioxide, where, when expressing Ba and S in the catalyst in terms of BaO and SO<sub>3</sub>, respectively, the molar ratio of SO<sub>3</sub> to BaO in the catalyst is 1 or higher. |
