This method comprises the steps of forming the boundary layer used for providing a gap between the movable member and the substrate above the heat generating member on the substrate, of laminating the movable member on the boundary layer so as to position the free end above the heat generating member, at the same time fixing the movable member on the substrate, and of forming the gap between the movable member and the heat generating member by use of the boundary layer. With the structure thus arranged, there is no need for the step to position the movable member with the substrate, and also, the movable portion of the movable member is separated from the substrate after the movable member is formed on the substrate and incorporated in the liquid discharge head so as to implement arranging the interior of each liquid flow path finer and more precisely.
