PROBLEM TO BE SOLVED: To obtain a mixed wool formed body by recycling materials tending to be disposed of conventionally and serving as function-imparting additive materials, in view of the fact that, as formed products using fibers as raw materials, three-dimensional formed products obtained by heat treatment of non-thermoplastic fibers and thermoplastic fibers have been known, however, these products have been demanded for performance improvements including human body blood circulation improvements owing to fragrance emission and/or magnetic force and cushioning improvements and also demanded for recycling polyurethane foam and waste refuses such as woodchips. SOLUTION: The mixed wool formed body is obtained by incorporating an additive material 19 having a length of 10-100 mm and a diameter of 10μm to 20 mm in mixed wool comprising thermoplastic fibers 20 and non-thermoplastic fibers 21 followed by carrying out a heat treatment to include the additive material in the mixed wool. In this mixed wool formed body, it is preferable that the additive material account for 2-40 wt.% of the whole mixed wool formed body, and the additive material is e.g. polyurethane foam, tourmaline mineral-containing rubber, hinoki cypress chips, fragrant wood, active carbon fiber, magnet-containing rubber.
