  A large cylindrical cadmium molybdate crystal with natural isotopic abundance
has been used to fabricate a scintillating bolometer. The measurement was
performed above ground at milli-Kelvin temperature, with simultaneous readout
of the heat and the scintillation light. The energy resolution as FWHM has
achieved from 5 keV (at 238 keV) to 13 keV (at 2615 keV). We present the
results of the $\alpha$ versus $\beta$/$\gamma$ events discrimination. The low
internal trace contamination of the $\mathrm{CdMoO_4}$ crystal was evaluated as
well. The detector performance with preliminary positive indications proves
that cadmium molybdate crystal is a promising absorber for neutrinoless double
beta decay scintillating bolometric experiments with $\mathrm{{}^{116}Cd}$ and
$\mathrm{{}^{100}Mo}$ nuclides in the next-generation technique.
