Electric conductor patterns having inner leads arranged at a pitch of not larger than 60 μm are formed on a front surface of an insulating layer of a tape carrier for TAB. A reinforcing layer of stainless steel foil is formed on a rear surface of the insulating layer so as to be extend along a lengthwise direction at opposite side edge portions in a widthwise direction of the insulating layer. Accordingly, both dimensional accuracy and positional accuracy can be improved at the time of carrying the tape carrier for TAB or at the time of mounting and bonding electronic parts though the insulating layer can be formed so as to be thin.

A method for printing corrugated cardboard sheets is effected by transferring the corrugated cardboard sheets while jetting ink droplets from ink jet nozzles onto the corrugated cardboard sheets to form dots thereon. Said method comprises the steps of transferring the corrugated cardboard sheets one by one while at the same time sucking one flat surface of each of the corrugated cardboard sheets, and adjusting the relationship among the velocity at which the corrugated cardboard sheets are transferred, the suction force of the corrugated cardboard sheets, and the distance between the ink jet nozzle and the other corrugated surface of each of the corrugated cardboard sheets in accordance with the configuration of the said other corrugated surface and the desired DPI of dots to be formed on the said other corrugated surface. As a result, the ink droplets are jetted toward the said other corrugated surface to be printed thereon.

A thin film piezoelectric element has a laminate including a piezoelectric film and a pair of electrode films placed so as to sandwich the piezoelectric film in between, a resin film formed so as to cover the laminate, and an electrode formed on the resin film and electrically connected to the electrode film. The resin film is formed so that a thickness of a region where the electrode is formed is larger than a thickness of a region corresponding to a displaced portion of the laminate.

The width of a particular part (A) of a strip conductor 2 of a wiring circuit board for mounting is reduced, wherein the strip conductor is exposed to form a stripe pattern, so that individual conductor can be connected to electrode E of an electronic component. The particular part (A) is one section in the longitudinal direction of a strip conductor having a long end, which part includes an area overlapping an electrode which is connected to a short end and transferred in parallel in the strip width direction up to the position on the strip conductor having a long end. Due to this constitution, a structure capable of suppressing a short circuit between an electrode and a wiring pattern can be afforded to a wiring circuit board, even to an electronic component having an electrode formed in high-density and in a zigzag arrangement pattern, which comprises an area overlapping an electrode.

A multilayer flexible wired circuit board that can provide high density wiring and also can provide reduction in thickness and size, and a producing method thereof. A four-layered flexible wired circuit board is produced by preparing a double-sided substrate in which a first conductor layer and a second conductor layer are laminated on both sides of a first insulating layer; preparing a first single-sided substrate in which a third conductor layer is laminated on one surface of a second insulating layer and a second single-sided substrate in which a fourth conductor layer is laminated on one surface of a third insulating layer; bonding the first conductor layer and the third conductor layer to each other through a first thermosetting adhesive layer; and bonding the second conductor layer and the fourth conductor layer to each other through a second thermosetting adhesive layer.
