Zusammenfassung:	To provide a method of producing a composite material allowing for forming a metal film that is less changed in hue even if formed on a base material having low heat resistance and suppressed against an occurrence of electro-chemical migration under conditions of high temperature and humidity, and a device using a composite material obtained by the producing method.SOLUTION: A method of producing a composite material including a base material and a metal film formed on the base material includes a step of forming a metal film on a the base material by applying a metal fine-particle containing ink to the base material. In the method of producing a composite material, the base material has a heat-resistant temperature of equal to or lower than 130°C, the metal fine-particle containing ink contains a metal fine particle A dispersed with polymer B, the metal fine particle A has a volumetric average particle size DA of 10-60 nm, the metal film has a sectional porosity of 2-30 area%, and the metal film has a metal content of equal to or higher than 90 mass%.SELECTED DRAWING: None 【課題】耐熱性が低い基材に形成する場合であっても、色相変化が少なく、かつ高温高湿条件下でのエレクトロケミカルマイグレーションの発生が抑制された金属膜を形成することができる複合材料の製造方法、及び該製造方法により得られる複合材料を用いるデバイスを提供する。【解決手段】基材と該基材上に形成された金属膜とを含む複合材料の製造方法であって、該基材に金属微粒子含有インクを塗布して、該基材上に金属膜を形成する工程を含み、該基材の耐熱温度が１３０℃以下であり、該金属微粒子含有インクがポリマーＢで分散されてなる金属微粒子Ａを含有し、該金属微粒子Ａの体積平均粒径ＤAが１０～６０ｎｍであり、該金属膜断面の空隙率が２～３０面積％であり、該金属膜中の金属の含有量が９０質量％以上である、複合材料の製造方法である。【選択図】なし
