Embodiment 1
[0093] Using a twin-shaft mixer (45 mm φ, L / D = 42), melt-mix the components with the mixing formula shown in Example 1 in Table 1, melt-extrude in the form of strands, and then cool and cut the melted strands to make small pellets . In the resin composition described in Table 1, in 100 parts by weight of the resin component, 0.5 part by weight of oleic acid amide is mixed as a lubricant, and 1 part by weight of tetrakis [3-(3,5-bis tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester.
[0094] Eight flat conductors (flat tinned copper wires) with a width of 1.2 mm and a thickness of 0.15 mm are fed from the supply bobbin group to the concentrator, and arranged in parallel at a conductor pitch of 2.0 mm. Then, the eight flat conductors arranged in parallel were conveyed to a mold of a melt injection molding machine, and small pellets of the resin composition shown in Example 1 in Table 1 were supplied from the melt injection molding machine for insulating coating.

Embodiment 2~8
[0097] Each flexible flat cable was produced in the same manner as in Example 1, except that the mixing recipe of the flame-retardant resin composition in Example 1 was changed to that shown in Examples 2 to 8 in Table 1. The results are shown in Table 1.
