Unnecessary and the transfer device a filter paper

PROBLEM TO BE SOLVED: To provide a transfer device requiring no filter paper, capable of simply obtaining good transfer results, even if an air bubble absorbing means such as the filter paper is not used. SOLUTION: The transfer device 100 is constituted so as to transfer a sample to the transfer film 103 arranged in contact with a sample-containing gel 102 by applying voltage to the gel 102 through an electrolyte. The anode electrode 104 of a pair of electrodes consisting of the anode electrode 104 and a cathode electrode 101 contains iron. Since iron contained in the anode electrode 104 acts as a sacrifice oxidizing agent when transferred, the occurrence of air bubbles caused by the electrolysis of the electrolyte is suppressed.
