Abstract: A method and an apparatus for producing a cell tissue of blood vessels or the like with the use of an electrostatic ink jet phenomenon are provided. A pattern generator for cell tissue patterning on a substrate includes at least one vessel for holding a solution containing materials used for cell tissue formation, a substrate that is an object of patterning, and a pattern generator including a voltage applying unit for applying a voltage to the vessel. The voltage is applied to the vessel by the voltage applying unit to generate an electric field between the vessel and the substrate, causing the solution to be ejected from the vessel as a result of an electrostatic ink jet phenomenon and allowing the ejected solution to adhere to the substrate.
