To provide a tableware case capable of retaining a perfectly clean state after washing tableware such as chopsticks till a user uses, and capable of giving senses of cleanliness and security to the user of tableware such as the chopsticks.

A bacteria elimination agent M soaked in a mat 23 is evaporated little by little, passes through small holes 11 and flows into a tableware storage part 13. The bacterial elimination agent thus sterilizes, eliminates virus and deodorize chopsticks C in the tableware storage part 13 and retains the inside of the tableware storage part 13 clean other than the chopsticks C. A person using chopsticks C takes out the chopsticks C stored in the tableware storage part 13 from a tableware storage-side opening 5a that is opened by opening an opening/closing lid 17. Even if the person's fingers touch chopsticks C other than the chopsticks to be taken out and the inner faces of the tableware storage part 13, the chopsticks C inside the tableware storage part 13 and the inner faces of the tableware storage part 13 are retained clean by the operation of the bacteria elimination agent M.
