Abstract
An inkjet printing head which is capable of being assembled efficiently and easily. In the inkjet printing head, a main frame has a hollow portion for receiving a flexible cable therein, and a sub-frame has a rimmed window for receiving a flexible member. The main frame and sub-frame are combined such that the flexible cable and flexible member are sandwiched therebetween. The hollow portion of the main frame, the flexible cable and the rimmed window of the sub-frame have the same shape so that these members can be reliably positioned with respect to one another. Electrodes on the flexible cable are pressed, with a uniform pressure, to piezoelectric elements of a head assembly attached to the main frame.
