Zusammenfassung:Provided is a fiber having superior bulkiness despite being a synthetic fiber, and wadding. The fiber contains inorganic particles having an average particle diameter of 1 µm to 20 µm within the fiber and fiber pores having a maximum width of 0.1 µm to 5 µm and maximum length of 1 µm to 50 µm are formed in fiber cross-sections in the axial direction of the fiber. The wadding contains a fiber A, and the content of fiber A in the wadding (100% by weight) is 50% by weight to 100% by weight, down power is 270 cm/g to 400 cm/g, and the fiber A contains inorganic particles having an average particle diameter of 1 µm to 20 µm within the fiber.
