A valve unit includes a valve portion arranged in a laminate body operable to open and close a flow passage; a drive portion that generates drive force for driving the valve portion; and a transmission portion arranged between the valve portion and the drive portion for transmitting the drive force of the drive portion to the valve portion. The laminate body includes: a first plate member including the drive portion; and a second plate member including a hole functioning as part of the flow passage; and a third plate member arranged above the second plate member and including a plate spring so as to urge the valve portion to a closing position. The valve portion pivots and inclines about a position in contact with the plate spring based on the drive force from the drive portion.
