  We report a method of correcting a near-infrared (0.90-1.35 $\mu$m)
high-resolution ($\lambda/\Delta\lambda\sim28,000$) spectrum for telluric
absorption using the corresponding spectrum of a telluric standard star. The
proposed method uses an A0\,V star or its analog as a standard star from which
on the order of 100 intrinsic stellar lines are carefully removed with the help
of a reference synthetic telluric spectrum. We find that this method can also
be applied to feature-rich objects having spectra with heavily blended
intrinsic stellar and telluric lines and present an application to a G-type
giant using this approach. We also develop a new diagnostic method for
evaluating the accuracy of telluric correction and use it to demonstrate that
our method achieves an accuracy better than 2\% for spectral parts for which
the atmospheric transmittance is as low as $\sim$20\% if telluric standard
stars are observed under the following conditions: (1) the difference in
airmass between the target and the standard is $\lesssim 0.05$; and (2) that in
time is less than 1 h. In particular, the time variability of water vapor has a
large impact on the accuracy of telluric correction and minimizing the
difference in time from that of the telluric standard star is important
especially in near-infrared high-resolution spectroscopic observation.
