An insulated wire includes a conductor, and an insulation layer provided around the conductor. The insulation layer includes an inner layer located on a conductor side and an outer layer provided around the inner layer. The inner layer includes a halogen-free resin composition including a base polymer (A). The outer layer includes a cross-linked body obtained by cross-linking a halogen-free flame-retardant resin composition including a base polymer (B) and a halogen-free flame retardant. The base polymer (A) includes a thermoplastic resin (a1) having an aromatic ring in a backbone chain. The base polymer (B) includes a polyolefin component. A thickness of the inner layer is not less than 0.03 mm and not more than 70% of a thickness of the insulation layer.
摘要:
It is an object of the present invention to ensure a high water-stopping property of a wire harness including a waterproofing connector section that is molded from a resin, by suppressing a variation in the outer size of a seal section of the connector section. The connector section is made from a first synthetic resin that is insert-molded with a part of a terminal fitting of the terminated electric cable used as an insert section. A water-stopping section is made from a second synthetic resin that is insert-molded with a section extending from a part of the terminal fitting to an insulation coating of the terminated electric cable used as an insert section. The seal section is made from the second synthetic resin that is insert-molded with a part of the connector section used as an insert section. The second synthetic resin is softer than the first synthetic resin.

A transparent conductive film 1 includes, in this order, a transparent substrate 2, a first optical adjustment layer 4, an inorganic layer 5, and a transparent conductive layer 6. The first optical adjustment layer 4 has refraction nC lower than refraction nA of the transparent substrate 2, and thickness TC of 10 nm or more and 35 nm or less. The inorganic layer 5 has refraction nD that is lower than the absolute value |nC×1.13| of a value obtained by multiplying the refraction nC of the first optical adjustment layer 4 by 1.13.
