METHOD FOR PRODUCING COMPOSITE MATERIAL

The present invention relates to a method for producing a composite material comprising a base material and a metal film formed on the base material, the method comprising a step of applying an ink containing metal fine particles to the base material and forming the metal film on the base material, the heat resistance temperature of the base material being 130 DEG C or less, and the heat resistance temperature of the metal film being 30 DEG C or less. The ink containing metal microparticles contains metal microparticles A in which a polymer B is dispersed, the volume average particle diameter DA of the metal microparticles A is 10-60 nm, the porosity of the cross section of the metal film is 2-30 area%, and the metal content in the metal film is 90 mass% or more. 本发明涉及一种复合材料的制造方法，其是包含基材和形成于该基材上的金属膜的复合材料的制造方法，其中，包括向该基材涂布含有金属微粒的油墨，在该基材上形成金属膜的工序，该基材的耐热温度为130℃以下，该含有金属微粒的油墨含有以聚合物B分散而成的金属微粒A，该金属微粒A的体积平均粒径DA为10～60nm，该金属膜截面的空隙率为2～30面积％，该金属膜中的金属的含量为90质量％以上。
