摘要

PCT No. PCT/JP95/01619 Sec. 371 Date Feb. 13, 1998 Sec. 102(e) Date Feb. 13, 1998 PCT Filed Aug. 14, 1995 PCT Pub. No. WO97/06848 PCT Pub. Date Feb. 27, 1997An iontophoresis electrode structure comprising has both a polarization electrode and a non-polarization electrode, wherein both electrodes can be switched freely while the electricity is turned on. The present electrode structure makes it possible to transfer biologically active substances and drugs into a living body through the skin and the mucous membrane in a sufficient amount and safety by employing both a polarization electrode and a non-polarization electrode as iontophoresis electrodes according to a proper switch, and can transfer biologically active substances and drugs through the skin and the mucous membrane effectively without causing irritation.
