Patent ID: 8210652

Claim:
A printing head, comprising: a printing element for applying energy to liquid in order to eject the liquid through an ejection port; an electrode terminal formed at an end of a wiring extending from the printing element for transmitting electric energy to the printing element; and a lead for transmitting a driving signal for driving the printing element, the lead being arranged in a position corresponding to the electrode terminal; and a bump connecting between the electrode terminal and the lead, wherein the connection between the electrode terminal and the bump is performed by applying ultrasonic oscillation to a connecting part between the electrode terminal and the bump so that a main oscillation direction is a first direction while the electrode terminal is in contact with the bump, and the connection between the lead and the bump is performed by applying ultrasonic oscillation to a connecting part between the lead and the bump so that the main oscillation direction is a second direction intersecting with the first direction while the lead is in contact with the bump.
