We studied matter mixing by Rayleigh-Taylor instability in the jetlike supernova explosion by numerical calculations of two-dimensional hydrodynamics. We found that (1) the asymmetric explosion with 5% initial perturbation causes the same degree of matter mixing as the spherical one with 30% perturbation, and that (2) 30% initial perturbation in the jetlike explosion is sufficient to explain the mixing in SN 1987A suggested by many observations without any subsequent instability such as nickel bubble formation.
