FLEXIBLE CIRCUIT BOARD AND METHOD OF MANUFACTURING THE SAME, DROPLET DISCHARGE HEAD, DROPLET DISCHARGE DEVICE, AND SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a flexible circuit board and a method of manufacturing the same, which are for achieving good connection and improving mounting efficiency; a high reliability and miniaturized droplet discharge head; and a droplet discharge device and a semiconductor device, which secure long-term connection reliability.

SOLUTION: The droplet discharge head 1 is composed of a plurality of terminals each arranged in one direction on a first surface of a flexible substrate 71, and includes a pair of terminal rows arranged in substantially parallel with each other and wiring patterns each extended from each terminal of the pair of terminal rows. The droplet discharge head 1 includes a flexible circuit board 27 in which the terminal rows are arranged oppositely via a through-hole 80 formed by passing through the flexible substrate 71.
