Zusammenfassung:	There are provided a pump unit with a reduced number of components and capable of simplifying a manufacturing process thereof, and a method for manufacturing the pump unit. The pump unit (1) comprises a pump (2) including a piezoelectric element (4) and a discharge mechanism (5) for discharging fluid according to operation of the piezoelectric element (4), and a valve mechanism (3) attached to the pump (2). The discharge mechanism (5) and the valve mechanism (3) are separately formed by joining a plurality of metal layer pieces (22) to (37) stacked in a predetermined stacking direction by diffusion welding, and are secured to each other by diffusion welding.
