PROBLEM TO BE SOLVED: To provide a wire for coil which can enhance the density of flux passing therethrough, and the performance of a motor, and to provide a motor using such a wire for coil, an electronic apparatus and a robot.SOLUTION: A wire 10 for coil includes a core 1 composed of a soft magnetic material and arranged in the center of the cross-section, a low electric resistance layer 2 composed of a low electric resistance material and formed to cover the outer peripheral surface of the core 1, and an insulation layer 3 formed to cover the outer peripheral surface of the low electric resistance layer 2. Preferably, the soft magnetic material has saturation magnetization of 1.2T-2.0T. Preferably, the electrical resistivity of the low electric resistance material is 1.5×10to 3×10&OHgr;m at 20°C. Preferably, the low electric resistance material contains at least one kind selected from a group consisting of Cu, Ag, Au, and Al. |
