An ink-jet head of the invention includes a head main body, an inflow port, an outflow port, an ink flow path, a nozzle, a heater and a guide unit. The ink flow path is formed inside the head main body to connect the inflow port and the outflow port. Ink flows in the inside of the ink flow path from the inflow port to the outflow port. The nozzle is formed on a side of the ink flow path. The heater is provided in the ink flow path. The heater generates a bubble pressure in the ink flow path, and causes the ink to be discharged from the nozzle. A bubble guide structure is provided in the ink flow path and guides the bubble pressure to the nozzle. The heater may be provided to be eccentric to the nozzle, or the heater may be disposed to be inclined. |
