To provide a washing/drying machine having superior dust removing performance and drying performance.

This washing/drying machine has: an inner tub 44 storing laundry 3 and rotatably provided in an outer tub 43; an air blowing fan 49 for sending air to the inner tub 44; heating means 55 for heating the air sent by the air blowing fan 49; a dust-proof filter 47 for catching lint or the like generated from the laundry 3; and dust removing body 48 attached to the inner tub 44 and removing the lint or the like caught in the dust-proof filter 47; and is configured to move the dust removing body 48 onto the dust-proof filter 47 by a centrifugal force generated when rotating the inner tub 44; for example, when the dust removing body 48 is set to move onto the dust-proof filter 47 and the rotating speed of the inner tub 44 increases to the rotation speed in the drying operation, the dust removing body 48 automatically comes into slide contact with the dust-proof filter 47 in the drying operation to efficiently and surely remove the lint or the like and prevent the lowering of the drying efficiency.
