Abstract

PURPOSE:To enable a defective part to be partially corrected, by a method wherein, the fixed number of recording electrodes are determined as a unit module, and a plurality of modules are combined to be of a required size to constitute a sheet of multi-needle recording head. CONSTITUTION:A plurality of ICs packaged on a ceramic substrate 21 is used as a unit module. On the ceramic substrate 21, a required number of positioning holes 22 and slots 23 are formed for enhancing an alignment accuracy. On a holder 24 to which the substrate 21 is to be fixed, positioning pins 25, 26 are mounted to be nested into the slot 23 referring to the positioning hole 22 of the substrate, whereby the substrate 21 is positioned to the holder 24. In this manner, the substrates 21 are mounted on the holder 24 of a required width to constitute a recording head 30 of a required size. A pressure by a pressurizing member 15 depressing down against a flexible printed board 10 is large enough to fix the substrates 21 to the holder 24. In this manner, the recording head composed of a plurality of ceramic substrates is allowed to be corrected by replacing only the defective substrate.
