Workshop on 'Nuclear Physics and Nuclear Chemistry of Superheavy Elements' was held in Advanced Science Research Center of JAERI at February 27-28 (2003). Efforts were paid to produce SHEs in several countries including Germany, Russia, France, and United States. In Japan, the production of element with Z=111 has been reported by RIKEN. In JAERI, investigations on fusion mechanism have been made in order to find an efficient way to produce SHEs. Chemistry on SHEs is quite active. In the SHE region, a wave function of outermost electron, which controls chemical properties of an element, is disturbed or changed by relativistic effects. This suggests that the SHEs have different chemical properties from those of lighter elements belonging to the same family. In the JAERI-tandem facility, chemistry of Rf and Db have been investigated by using actinide targets such as Cm. In the workshop, discussions on the current status and future plans for the heavy element research were made.
