The primoridal lithium abundance is known to be one of the best probes to test the standard as well as the non‐standard Big Bang nucleosynthesis theories, and to measure the nucleon abundance in the early universe in the standard Big Bang (SSB) model. We have obtained high‐resolution ((λ)/(δλ)≂100,000), high signal‐to‐noise (S/N≳1,500) spectra of SN 1987A around the Li:I λ6708 Å region, using the ESO 1.4m CAT and the Coudé Echelle Spectrograph. The non‐detection of any lithium feature in our sepctra places an upper limit on the lithium abundance. (AIP)
