Abstract: A molecule introducing apparatus is provided with a power supply circuit 20 for supplying power, a step-up transformer 30 which is supplied with power from the power supply circuit 20 and which outputs a high voltage, a switching transistor 22 that blocks off and allows the supply of power from the power supply circuit 20 to the step-up transformer 30 and which generates an instantaneous high voltage, and a pair of electrode probes 50 for applying the instantaneous high voltage generated at the step-up transformer 30 to a predetermined region in a body. The molecule introducing apparatus oscillates DNA arranged outside a cell by the instantaneous high voltage so as to introduce the DNA into the cell.

Abstract: A voltage generation circuit (20) is provided which generates a voltage. A voltage application circuit (30) is provided which has electrodes (11, 12) which are fed a respective voltage for causing creation of an instantaneous high electric field in a region of interest as a target such as a living body tissue or cell. The voltage application circuit (30) is high-impedanced for excitation of a free resonant circuit including the target. It is arranged such that the relative position of the target with respect to one of the electrodes (11, 12) is adjustable.
