| Summary:
A preliminary result of the solar axion search experiment at the University
of Tokyo is presented. We searched for axions which could be produced in the
solar core by exploiting the axion helioscope. The helioscope consists of a
superconducting magnet with field strength of 4 Tesla over 2.3 meters. From the
absence of the axion signal we set a 95 % confidence level upper limit on the
axion coupling to two photons $g_{agammagamma} < 6.0 times 10^{-10}
GeV^{-1}$ for the axion mass $m_a < 0.03$ eV. This is the first solar axion
search experiment whose sensitivity to $g_{agammagamma}$ exceeds the limit
inferred from the solar age consideration.
