A liquid jetting apparatus includes: a first head chip having first nozzles arranged in a nozzle arrangement direction; a second head chip having second nozzles arranged in the nozzle arrangement direction, and being arranged to overlap at least partially with the first head chip in an orthogonal direction orthogonal to the nozzle arrangement direction; a controller configured to control the first head chip and the second head chip to jet liquid from the first nozzles and the second nozzles; and power sources having different voltages, respectively. Each of the first nozzles and the second nozzles is driven by voltage supplied from one of the power sources, and the first head chip has a first overlapping portion and the second head chip has a second overlapping portion overlapping with the first overlapping portion in the orthogonal direction.
