A partial denture mounting structure which can reduce the load on a clasped tooth, which is highly durable, which facilitates occlusal adjustment, and which can be fabricated without a high level of skill is provided primarily. The partial denture mounting structure includes a denture base (35) that holds an artificial tooth, and a fitting member (11) fixedly secured to the denture base and configured to be fitted to a clasped tooth (31). The fitting member (11) is cylindrical. The cylindrical member is fitted to the clasped tooth (31) so as to cover the side peripheral surface of the clasped tooth, making at least a top portion (31t) of the clasped tooth exposed from the cylindrical member.
