Claim Text:
1. A nucleic-acid extraction method, the method comprising: inserting a sample containing a nucleic-acid into a negative-electrode side area between a dialysis membrane and a negative electrode; performing an ultrasonic process on the sample containing a nucleic-acid and adjusting the time and frequency of the ultrasonic process based on the type of the sample; adsorbing foreign substances contained in the sample using an adsorption carrier after performing the ultrasonic process; and blocking an electrophoresis movement of the nucleic acid to condense the nucleic-acid on a boundary face of the dialysis membrane after adsorbing the foreign substances, wherein bead particles are inserted into the negative-electrode side area before the sample containing the nucleic-acid is inserted into the negative-electrode side area.
