An inkjet device includes a pressure chamber that stores ink, a piezoelectric element that is away from the pressure chamber in a first direction, and a diaphragm that is disposed between the pressure chamber and the piezoelectric element in the first direction. The diaphragm includes a pressure receiving portion. The pressure receiving portion includes a top portion and a base portion. The top portion is in contact with the piezoelectric element. The base portion is connected to a body of the diaphragm. A width of the base portion is larger than a width of the top portion in a second direction that is at least one direction perpendicular to the first direction.
