PROBLEM TO BE SOLVED: To conduct electroporation by making an electric field which is impressed on a target cell uniform as much as possible, in such a simple system that only a constant-voltage power source is used in the system without requiring a pulse generater. SOLUTION: In the system, a suspension containing the target cell and an objective introduced substance is flown in the direction from a flow path 15 to another flow path 16 and, simultaneously, electrodes 12 and 13 are impressed with a direct-current voltage, and therefore a constant electric field is formed inside a flow path between the electrodes 12 and 13, so that the pulsed electric field of a square wave shape is impressed on the target cell which flows in the flow path between the electrodes 12 and 13.
