[0101] Figure 9A , 9B are sectional views for explaining the structure of the liquid discharge head manufactured according to the method of manufacturing the liquid discharge head according to the second embodiment of the present invention. The liquid discharge head according to this embodiment is mainly different from the liquid discharge head of the first embodiment in that the width of the electrode layer on the device substrate is smaller than that of the movable member. The following mainly describes the differences from the first embodiment in Figure 9A In and 9B, the same reference numerals are used for the same parts as those of the first embodiment.
[0102] In the liquid discharge head according to this embodiment, as Figure 9A , 9B, in the direction perpendicular to the liquid flow direction of the liquid flow path 7 on the movable member 6 and parallel to the width W of the surface of the device substrate 1 6 Greater than the width W in the direction perpendi...
