Abstract
Ends (-) of projections () do not contact a first substrate (), forming a gap between the ends (-) and the first substrate (). The internal capacity of a suction pump () can be increased by an amount by which the projections () are shortened, compared to a conventional structure in which pillars are formed to connect the ceiling and bottom of the cavity of a capillary pump. The capacity of the suction pump () can be increased without enlarging the planar shape. Further, the ends (-) of the projections () do not contact the first substrate (), forming a gap between them. An impurity can pass through the gap, and clogging of the inside of the suction pump () with the impurity can be prevented, realizing a stable operation.
