Abstract
A fluid control device includes a pump and an external structure. The pump includes an actuator, a top portion opposed to the actuator such that a gap is disposed therebetween in the thickness direction, and a side wall plate extending from the top portion in the thickness direction and supporting a vibration member. The actuator includes the plate-like vibration member and a piezoelectric element configured to cause the vibration member to vibrate in the thickness direction. The top portion includes a projection portion and a fixation portion projecting beyond the side wall plate in an outward direction perpendicular to the thickness direction. The top portion is fixed to an external structure outside the projection portion.
