Abstract: A metal strip contains a metal magnetic material as a main component, and is formed such that a surface roughness of one main surface is higher than a surface roughness of an other main surface. The other main surface is formed in a smooth surface having a high surface smoothness, and the one main surface is subjected to surface treatment such that a striped pattern composed of a recessed portion and a protruding portion is continuously formed. After a continuous strip is made by a single-roll liquid quenching method, the striped pattern is formed by subjecting one main surface of the continuous strip to surface treatment. A magnetic core is obtained by winding the metal strip in an annular shape, and a coil component, such as a common mode choke coil, is obtained by using the magnetic core. Thus, the metal strip has sufficient toughness and good mechanical strength.
