In the embodiment shown in FIG. 7A, a frame-shaped region 82 is defined by the liquid repellent film 80 on the upper surface of the substrate 60, and a liquid (not shown) is stored in this region 82. Then, when an ultraviolet ray or a laser beam is applied to an arbitrary position of the liquid repellent film 80, for example, the opening portion 84 indicated by the diagonal lines, the opening portion 8
The liquid repellent film of No. 4 is decomposed to become lyophilic, and the liquid in the area 82 is discharged to the outside of the area 82 through the opening 85. Therefore, the liquid in the area 82 can be caused to flow out at an arbitrary timing.
