  A new experimental scheme is proposed to search for almost monochromatic
solar axions, whose existence has not been discussed heretofore. The axions
would be produced when thermally excited $^{57}$Fe in the sun relaxes to its
ground state and could be detected via resonant excitation of the same nuclide
in a laboratory. A detailed calculation shows that the rate of the excitation
is up to order 10 events/day/kg-$^{57}$Fe. The excitation can be detected
efficiently using bolometers or liquid scintillators.
