ABSTRACT:
A printed circuit terminal device which includes a terminal array having very fine pitch between lead lines from a circuit portion including a flexible printed circuit board having a terminal array pattern which corresponds to the terminal array and wiring pattern and which are arranged to alternately extend from two sides of the terminal array pattern thus changing the pitch of the wiring pattern on the flexible printed circuit board to be twice that of the pitch of the wiring pattern of the terminal array. This allows a circuit to be easily and reliably coupled to the electrical terminals having very fine pitch and the formation of the wiring pattern of a coupling portion with the circuit portion can be easily performed and results in an arrangement of very small size. The flexible printed circuit board can be manufactured at low cost and the yield can be increased. Also, circuit elements such as resistors can be mounted on the wiring pattern without changing the wiring pitch.
