A665 at a redshift 0.1816 was observed with ASCA for about 40ks. Observed spectrum is well fitted by thin thermal plasma (Raymond-Smith) model of kT\sim9keV and Iron abundance\sim0.27 cosmic. Fe K line emission is detected with high confidence. A model consisting a thermal bremsstrahlung continuum and two gaussian-profile emission lines have been fitted to the GIS (Gas Imaging Spectrometer) spectrum and the best fit line center energies are \sim6.70keV (Kalpha) and \sim8.08keV (Kbeta) in the rest frame. Those equivalent widths are \sim220eV and \sim210eV respectively. The center energies and intensity ratio are not inconsistent with the model predicted value at this temperature since large error, but are relatively small.
