摘要：
An ink jet print head, which can prevent test terminals from coming into contact with ink or moisture and thus being corroded or damaging other circuits or wires, includes a nozzle forming member that is located in the vicinity of an area with the test terminals arranged therein and is separated from a nozzle forming member located in the remaining area so as to have a reduced volume.
