摘要：
本发明提供绝缘电线以及使用其的线圈和电子/电气设备，该绝缘电线在导体的外周面上具有包含热塑性树脂的绝缘包覆层，该导体的截面形状为矩形、具有长边和短边以及曲率半径为Rc的角部，该绝缘电线的特征在于，上述导体的横截面长边的在上述导体的轴线方向连续的面上所包覆的上述绝缘包覆层的厚度t1(μm)、上述导体的横截面短边的在上述导体的轴线方向连续的面上所包覆的上述绝缘包覆层的厚度t2(μm)、以及上述绝缘包覆层的角部的厚度t3(μm)处于下式(1)的关系，式(1)，t3/{(t1+t2)/2}≧1.2上述t1(μm)和t2(μm)各自独立地为20μm以上50μm以下，并且上述导体截面积Sc(mm2)相对于上述绝缘电线截面积Sw(mm2)之比的值处于下式(2)的关系。式(2)，1.0>Sc/Sw≧0.8。
摘要（英）：

An insulated wire having an insulating coat layer comprising a thermoplastic resin on the outer peripheral surface of a conductor having a rectangular cross-sectional shape and also having a long side, a short side, and a corner portion having a curvature radius Rc, wherein a thickness t1 (µm) of the insulating coat layer covered on the surface which is continuing in an axial direction of the conductor, and which layer includes a long side of a transverse section of the conductor, a thickness t2 (µm) of the insulating coat layer covered on the surface which is continuing in the axial direction of the conductor, and which layer includes a short side of the transverse section of the conductor, and a corner portion thickness t3 (µm) of the insulating coat layer satisfy the relationship of formula (1): t 3 / t 1 + t 2 / 2 ‰¥ 1.2 wherein the t1 (µm) and t2 (µm) are each independently 20 µm or more and 50 µm or less, and wherein a ratio of a cross-sectional area Sc (mm 2 ) of the conductor to a cross-sectional area Sw (mm 2 ) of the insulated wire satisfies the relationship of formula (2) 1.0 > Sc / Sw ‰¥ 0.8 ; as well as a coil and an electric or electronic equipment using the same.
