The electronic states around vortex cores in high-Tc superconductors are studied using the two-dimensional t-J model. It is found that the region around the core where the zero-energy peak (ZEP) can be seen in the local density of states (LDOS) becomes smaller as the system approaches the optimum-doped from the overdoped region. We also show that the LDOS without the ZEP can be found in the vortex cores near the optimum doping region, where the vortex cores becomes sufficiently small.
