PROBLEM TO BE SOLVED: To prevent an offensive odor from being generated in an operation of an actual air-conditioner by generating an adsorbed molecule or organic substance of an offensive smell as an odor, from titanium oxide itself, even under the condition that it is not irradiated with light such as an ultra-violet ray, in a fin and tube type heat-exchanger used for a heat pump air-conditioner or the like. SOLUTION: A compounding ratio of a binder to the titanium oxide in a titanium oxide layer 13 formed using the binder on a fin 12 surface for constituting the fin and tube type heat-exchanger is brought into a range from 60:40 to 50:50 by weight ratio of solid contents thereof so as to optimize the compounding ratio of the binder to the titanium oxide, and the offensive odor is prevented from being generated in the operation of the actual air-conditioner by generating the adsorbed molecule or organic substance of the offensive smell as the odor, from the titanium oxide itself, even under the condition where not irradiated with light such as the ultra-violet ray.
