Provided are: an electromagnetic wave-transmitting metal member which has both metallic luster and electromagnetic wave transmissivity, and which is able to be easily produced at low cost; an articlewhich uses this electromagnetic wave-transmitting metal member; and a method for producing an electromagnetic wave-transmitting metal film. An electromagnetic wave-transmitting metal member accordingto the present invention comprises a metal layer and a crack layer; and the metal layer and the crack layer have a plurality of linear cracks, which are substantially parallel to each other, in respective surfaces. The linear cracks of the metal layer and the linear cracks of the crack layer penetrate the respective layers in the thickness directions, and are continuous in the thickness directions. 本发明提供种制造成本低廉且制造容易、兼备金属光泽和电磁波透过性的电磁波透过性金属部件、使用该部件的物品、以及电磁波透过性金属膜的制造方法。电磁波透过性金属部件包含金属层和裂缝层，金属层和裂缝层在各自的各面内具有实质上相互平行的多条直线状裂缝。金属层的直线状裂缝与裂缝层的直线状裂缝在厚度方向上贯通各自的层且在厚度方向上连续。
