PROBLEM TO BE SOLVED: To achieve downsizing of a droplet ejection head, a droplet ejection device, and an image forming device. SOLUTION: According to the structure of an ink-jet recording head 32 or the droplet ejection head, a connection wire 86 is arranged on internal walls of ink feeding through holes 112 and 44 which are channels for feeding ink in an ink pool chamber 38 into pressure chambers 50, and the connection wire 86 connects between a metallic wire 90 to which a driving IC 60 is connected and an upper electrode 54, to thereby electrically connect between the upper electrode 54 and the driving IC 60. Accordingly, compared with the case where a wiring through hole is formed separately from an ink channel, the number of holes to be formed in a top board 41 is reduced, and therefore an electric wire region is expanded, which leads to downsizing of the ink-jet recording head 32.
