From the magnetic-field dependence of the flux-flow resistivity, we found that a barometer of electronic states inside the vortex core $\\omega_{0}\\tau_{\\rm core}$ is $1\\pm0.5$, suggesting that the vortex core of pure FeSe is in the moderately clean regime contrary to the expectation of the super-clean core.
