Abstract
To generate an amount of heat uniformly in respective heaters which are selectively driven to eject ink droplets from the corresponding nozzles, a bypass common line is connected to a common conductor line with at least one connection conductor line. The heaters are connected between an LSI driver circuit and the common conductor line. The common conductor line and the connection conductor lines are made from nickel and the bypass common line is made from aluminum. Alternatively, the common conductor line may be of a three-lay structure having a first layer of a thin-film aluminum, a second layer of a Ta--Si--O alloy thin-film deposited to cover the first layer, and a third layer of a nickel thin-film deposited on the second layer.
