We obtained an optical spectrum (range 375-830 nm) of SN 2018ie (=kait-18A),discovered by Lick Supernova Survey, on UT Jan. 19.81 2018 with the 2.16-m telescope (+BFOSC) at Xinglong Station of National Astronomical Observatories of China (NAOC). The spectrum is consistent with that of a type Ic supernova at around the maximum light. Cross-correlation with a library of supernova spectra using the GELATO (Harutyunyan et al. 2008, A&A, 488, 383) tool shows that it matches with a few broadlined SNe Ic at a few days before the maximum light. Our classification spectrum is also posted on the IAU Transient Name Sever: https://wis-tns.weizmann.ac.il/object/2018ie
