UIrGe is an antiferromagnet crystallizing in the same orthorhombic structure as the ferromagnetic superconductors UCoGe and URhGe. We have studied physical properties on single crystal samples. Antifferomagnetic transition at 16.5 K was clearly observed, in consistent with the previous study. However, the results of electrical resistivity measurements obtained for our relatively high quality sample differ significantly from the previous reports, suggesting that the transport properties are significantly affected by the sample quality.
