Claim:
1. A method of manufacturing a liquid droplet ejecting head, the method comprising: preparing a base substrate, the base substrate being configured by: preparing a wiring substrate, the wiring substrate being configured with: bonding the first and second bottom surfaces of the first and second wiring forming portions to the base substrate so as to place the first terminal in an exposed state from the first inclined surface, place the second terminal in an exposed state from the second inclined surface, the third terminal in an exposed state from the third inclined surface, and place the fourth terminal in an exposed state from the fourth inclined; forming a first wiring on the first inclined surface and the first to surface to be directly and electrically connected to the first terminal, forming a second wiring on the second inclined surface and the first top surface to be directly and electrically connected to the second terminal, forming a third wiring on the third inclined surface and the second to surface to be directly and electrically connected to the third terminal, and forming a fourth wiring on the fourth inclined surface and the second top surface to be directly and electrically connected to the fourth terminal; and directly bonding an electronic circuit to the first through fourth wirings on the first and second top surfaces of the first and second wiring forming portions via a plurality of circuit terminals so that the first through fourth wirings are electrically connected to the plurality of circuit terminals.
