ABSTRACT:
A flow path forming member is formed with a recessed portion for forming an ink flow path. A junction surface of the flow path forming member is in a protruded state from a non-junction surface. The flow path forming member is composed of a transparent resin exhibiting transmissivity of laser beam. A tank holder is composed of a non-transmissive resin having no transmissivity of the laser beam. In a state where the flow path forming member is press-connected to the tank holder, the junction surface is welded by irradiating a periphery of the ink flow path with the laser beam from the side of the flow path forming member, thereby forming an ink flow path. Provided is an ink jet recording head in which the tank holder and the flow path forming member that serve to form the ink flow path are surely connected by a small number of steps without producing foreign matters within the ink flow path.
