   ASCA's new method of measuring magnetic fields of radio galaxies using
   the inverse-Compton scattered photon which does not assume
   equipartition has had a remarkable success. We propose further
   investigation on this problem with another giant radio galaxy, 4C73.08.
   This source has giant radio lobes with no knots or hot-spots, and no
   apparent core. In addition to these characteristics, radio polarization
   map of this galaxy has already been obtained. By comparing with the
   radio results, we can expect ASCA to bring us a new aspect of figuring
   out magnetic field of radio lobes.
