Abstract: A steering wheel having partially applied wooden outer covers, which can be produced without having the wooden outer covers scratched, and the like, and can be produced with high working efficiency, and a method for manufacturing the steering wheel are provided. Raw materials, from which wood members are formed, are attached at a rim portion of a core metal, and cores are formed in this state. Thereafter, the wood members are shaped from the raw materials. Further, resin pieces are attached in spaces between the wood members and the cores to limit displacement of the wood members. Then, the cores and the resin pieces are covered with covering portions. As described above, spaces are formed, and the cores are formed in a state in which the raw materials of the wood members are attached. This allows shaping of the wood members after formation of the cores.
