<P>PROBLEM TO BE SOLVED: To provide an insulated wire low in cost and excellent in flame resistance and thermal resistance. <P>SOLUTION: In an insulated wire, a periphery of a conductor is coated with at least two layers of insulating layers containing a cross-linked rubber, where an inner layer is an insulating layer containing a cross-linked silicone rubber, and an outer layer is an insulating layer containing a cross-linked fluororubber. Surface-treated magnesium hydroxide is preferably contained in at least one of the inner layer and the outer layer as a flame retardant, the surface-treated magnesium hydroxide being surface treated with a surface treatment agent comprising an organic polymer. A content of the surface-treated magnesium hydroxide in the insulating layers is preferably in a range of 0.1 to 100 pts. mass based on 100 pts. mass of the cross-linked rubber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
