본 발명은 내습 시험 실시 전후에서 저항 및 색도의 변화가 작은 금속화 필름 및 그 제조 방법을 얻는 것을 과제로 한다. 필름의 적어도 한쪽의 면에 필름측으로부터 동층과 방청층을 이 순서로 갖는 금속화 필름으로서, 방청층이 금속 티탄, 티탄산화물, 및, 이들의 혼합물로 이루어지는 군으로부터 선택되는 적어도 하나를 포함하고, 85℃ 85% RH 환경에서 3일 경과 후의 표면 저항 변화율이 20% 이하이며, 또한 상기 환경하에서 3일 경과 후의 색차(ΔE)가 6.5 이하인 금속화 필름에 의해 해결할 수 있다. The present invention addresses the problem of providing: a metallized film which shows a small degree of change in resistance and chromaticity before and after a moisture resistance test; and a method for producing the metallized film. The problem can be solved by a metallized film which comprises a film and a copper layer and an antirust layer arranged on at least one surface of the film in this order as observed from the film side, in which the antirust layer contains at least one component selected from the group consisting of metal titanium, a titanium oxide and a mixture thereof, the change ratio of the surface resistance after a lapse of 3 days under an environment of 85°C and 85% RH is 20% or less, and the color difference ΔE after a lapse of 3 days under the above-mentioned environment is 6.5 or less.
