  We show that YCr6Ge6, comprising a kagome lattice made up of Cr atoms, is a
plausible candidate compound for a kagome metal that is expected to exhibit
anomalous phenomena such as flat-band ferromagnetism. Resistivity,
magnetization, and heat capacity are measured on single crystals of YCr6Ge6,
and band structure calculations are performed to investigate the electronic
structure. Curie-Weiss-like behavior in magnetic susceptibility, T2 dependence
in resistivity, and a Sommerfeld coefficient doubly enhanced from a calculated
value indicate a moderately strong electron correlation. Interestingly, the
in-plane resistivity is twice as large as the interplane resistivity, which is
contrary to the simple expectation from the layered structure. Band structure
calculations demonstrate that there are partially flat bands slightly below the
Fermi level near the {\Gamma} point, which is ascribed to Cr 3d3z2-r2 bands and
may govern the properties of this compound.
