INSULATED WIRE AND METHOD FOR MANUFACTURING INSULATED WIRE

To provide an insulated wire that can easily inhibit occurrence of a defect in appearance and decrease in an insulating property, and a method for manufacturing the insulated wire.SOLUTION: The insulated wire comprises: a conductor 20 having an elongated shape; and an insulating coating 30 provided around the conductor 20, the insulating coating being formed by laminating multiple insulating layers 33 each including pores. If an average value of respective thicknesses of the multiple insulating layers 33 at a thick portion 30MAX of the insulating coating 30 having the largest thickness is defined as a first thickness and an average value of respective thicknesses of the multiple insulating layers 33 at a thin portion 30MIN of the insulating coating 30 having the smallest thickness is defined as a second thickness, then a thickness difference between the first thickness and the second thickness is 0.5 μm or less.SELECTED DRAWING: Figure 10 【課題】外観不具合の発生および絶縁性の低下を抑制しやすい絶縁電線および絶縁電線の製造方法を提供する。【解決手段】長尺状の形状を有する導体２０と、導体２０の周囲に設けられ、空孔を含む複数の絶縁層３３を積層させてなる絶縁被膜３０と、が設けられ、絶縁被膜３０の最も厚い部分である膜厚部３０ＭＡＸにおける複数の絶縁層３３のそれぞれの膜厚の平均値である第１膜厚と、絶縁被膜３０の最も薄い部分である膜薄部３０ＭＩＮにおける複数の絶縁層３３のそれぞれの膜厚の平均値である第２膜厚と、の差である膜厚差の値が０．５μｍ以下である。【選択図】 図１０
