We study gravitational wave from massive stellar core collapse with the spherical symmetry. We choose a perfect Huid with the realistic equation of state as a matter. The gauge-invariant approach is adopted to estimate the gravitational wave. Performing the numerical simulation, the waveform and the frequency for I = 2 are obtained. Analyzing the result of the simulation, we find that the gravitaional wave is produced at the core bounce. The frequency is about 1Hz.
