ABSTRACT:
A flexible circuit board (15) has one end portion (15a) soldered to a connection terminal row of a side surface (13e) of an ink-jet recording head (13), and extends upwardly from the ink jet recording head (13). The flexible circuit board (15) is bent at a midpoint at substantially right angles in the longitudinal direction of the flexible circuit board (15) to form a crease portion (15c). A forward end of the board (15) extends leftward, and is then folded back by 180 degrees to form a crease portion (15d). The forward end thereof extends rightward, and the forward end portion (15b) is soldered to a terminal row disposed on the back side of a COB substrate (24). A sheet-like double-faced tape having a drum-like cut-out shape is affixed to the crease portion (15c) in advance. When the flexible circuit board is folded along a crease line, the base material of the flexible printed wiring board at the cut-out part is adhered to the doubled-faced tape.
