A primary flow path forming member is provided with a groove which becomes a recording liquid supply path on a bottom surface thereof. A second flow path forming member is provided with an arm portion. The arm portion of the second flow path forming member is used as a cap for closing the opening of the groove which becomes the liquid supply path formed on the bottom surface of the prime flow path forming member. The primary flow path forming member and the second flow path forming member as described above are formed by injection-molding and bonded with each other by a bonding member. The bonding member is formed to cover a portion where the opening edge of the groove which becomes the recording liquid supply path, in the primary flow path forming member abuts on the arm portion of the second flow path forming member.
