    • 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 having a small width and a large length. 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 the periphery of 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.
    • 主流路形成构件在其底面设置有成为记录液供给路的槽。 第二流路形成构件设置有具有小宽度和大长度的臂部。 第二流路形成构件的臂部用作封闭形成在主流路形成构件的底面上的液体供给路径的槽的开口的盖。 如上所述的主流路形成部件和第二流路形成部件通过注射成型而通过接合部件彼此接合而形成。 接合部件形成为覆盖在主流路形成部件中成为记录液供给路的槽的开口边缘与第二流路形成部件的臂部抵接的部分的周边。
