To constitute a recording liquid supply path capable of avoiding a phenomenon such that a liquid droplet is not ejected even when air bubbles are mixed.

A groove being the recording liquid supply path 11a is provided in the bottom surface of a first flow path forming member 11. On the other hand, a second flow path forming member 12 includes a plurality of arm parts 12a being narrow and long parts. Each of the arm parts 12a has a shape along the contour of the groove being the recording liquid supply path 11a of the bottom surface of the first flow path forming member 11. Each of the arm parts 12a of the second flow path forming member 12 has a role as a cover for blocking the opening of the groove being the liquid supply path 11a formed in the bottom surface of the first flow path forming member 11. The first flow path forming member 11 and the second flow path forming member 12 are formed by injection molding and joined to each other by a joining member 13. The joining member 13 is formed so as to cover the circumference of a part in which the opening edge of the groove being the recording liquid supply path 11a of the first flow path forming member 11 is in contact with each of the arm parts 12a of the second flow path forming member 12.
