  We report the detailed physical properties of YRu3Si2 with the Ru kagome
lattice at normal and superconducting states. The results of resistivity and
magnetization show that YRu3Si2 is a type-II bulk superconductor with Tc ~ 3.0
K. The specific heat measurement further suggests that this superconductivity
could originate from the weak or moderate electron-phonon coupling. On the
other hand, both large Kadawaki-Woods ratio and Wilson ratio indicate that
there is a strong electron correlation effect in this system, which may have a
connection with the featured flat band of kagome lattice.
