An inkjet head maintenance device includes a base, a liquid supplier and a liquid collector. The base has an upper face disposed closely opposite a nozzle face of an inkjet head to form a liquid reservoir space during maintenance of the inkjet head. The base includes a liquid supply hole and a liquid collection hole that open to the upper face. The liquid supplier is configured to supply liquid from the liquid supply hole to the liquid reservoir space. The liquid collector is configured to collect the liquid in the liquid reservoir space from the liquid collection hole.

Inkjet head maintenance device and inkjet head maintenance method

With a nozzle being moved in one direction to a substrate unit, conductive ink is discharged out of a slit of the nozzle in a belt-like manner to the substrate unit. The conductive ink is discharged in a belt-like manner to the substrate unit on which a liquid-repellent region having a liquid repellency to the conductive ink and a lyophilic region having a lyophilic property to the conductive ink and having the same form as a desired circuit pattern are formed. Thereby, the conductive ink is applied to the lyophilic region, while the conductive ink is repelled at the remaining liquid-repellent region and flows into the lyophilic region.
