To provide an attached odor deodorizing apparatus easily removing attached odor on an object.

The attached odor deodorizing apparatus 1 includes: a casing 110; an ion generation element 130; an air-sending fan 120; a support part 111; and an ion delivery tube 112. The ion generation element 130 is arranged inside the casing 110 and generates H+(H2O)m (m is an optional integer) as a positive ion and O2-(H2O)n (n is an optional integer) as a negative ion. The air-sending fan 120 is arranged inside the casing 110 and delivers the positive ion and the negative ion generated in the ion generation element 130 together with gas. When the casing 110 is made to come close to clothes 10 from which the attached odor is to be removed, the casing 110, the support part 111 and the ion delivery tube 112 form a passage for circulating the gas delivered by the air-sending fan 120 along the surface of the clothes 10 together with the positive ion and the negative ion generated in the ion generation element 130.
