By using the full-field imaging soft x-ray microscopy, distribution of iodine which was accumulated in zone 5 of the endostyle ofa lancelet was observed. Then, x-ray energy of 600 and 640 eV, which are below and above of the M absorption edge of iodine(631 eV), were used to obtain the transmission images. From the difference of the transmittance of two images, observation of thedistribution of iodine with high resolution was attempted.
