An insulated wire having a thermosetting resin layer on the outer periphery of a conductor, and a thermoplastic resin layer on the outer periphery of the thermosetting resin layer, wherein a total thickness of the thermosetting resin layer and the thermoplastic resin layer is 100µm or more and 250µm or less, and a degree of orientation of a thermoplastic resin in said thermoplastic resin layer, that is calculated by the following Formula 1, is 20% or more and 90% or less; a coil and an electric and electronic equipment each having the insulated wire. Degree of orientation H % = 360 − ΣW n / 360 × 100
W n : A half width of orientation peak in the azimuth angle intensity distribution curve by X-ray diffraction
n: the number of orientation peak at a β angle of 0° or more and 360° or less.
