Conversion electron and photon measurements with the electrostatic and HPGe spectrometers, respectively, proved the existence of the 7.133+or-0.010 keV transition in <sup>160</sup>Ho. The conversion intensity ratios for ten outer subshells agree with predictions for the E1 multipolarity and exclude all other multipolarities with L<or=4. The M2 admixture is less than 6*10<sup>-6</sup> at the 99% confidence level. The transition intensity is roughly equal to the number of the <sup>160</sup>Er decays. The proposed 1<sup>+</sup>(p7/2<sup>-</sup>(523)+n5/2<sup>-</sup>(523)) level in <sup>160</sup>Ho is now confirmed.
