Abstract
An opposed surface of a first flow path forming member has a groove portion forming a supply passage, and a protruding portion protruding from the edge of the groove portion to form the side wall of the groove portion. An opposed surface of a second flow path forming member has a lid portion that abuts against the protruding portion of the first flow path forming member to cover the opening of the groove portion in the first flow path forming member. A joining member is formed by injection-molding of a resin to abut against an outer surface of the protruding portion of the first flow path forming member and the opposed surfaces of the first and second flow path forming members.
