Abstract: PROBLEM TO BE SOLVED: To provide a flexible printed wiring board which is used within an automatic transmission and is capable of preventing an insulating resistance between the adjacent conductor circuits from lowering even when it is soaked in lubrication oil.
SOLUTION: This flexible printed wiring board 1 is intended for use in lubrication oil. This board comprises a conductor circuit 4 provided on a base material 2, a terminal array 9 for electrically connecting the conductor circuit 4 and the outside of the flexible printed wiring board 1, and a cover lay film 7 for covering the conductor circuit 4. In addition, the terminal array 9 is covered with a coating material 11.

Abstract: PROBLEM TO BE SOLVED: To provide a flexible printed wiring board which has excellent electromagnetic shielding property and fire retardancy and superior step coverage and flexibility, has no environmental problems, and does not require a process such as thermal press for forming a shielding layer in manufacturing the same.
SOLUTION: The flexible printed wiring board comprises a base film, conductor circuit formed on the base film, cover lay for covering the conductor circuit, conductive paste layer formed on the cover layer, and top coat formed on the conductive paste layer. An adhesive layer interposed between the base film and the cover lay contains a non-halogen flame retarder, and the conductive paste layer has an average thickness of 22 μm or less and/or the top coat contains a non-halogen flame retarder.
