We observed an emergence of a region where the SC transition temperature ($T_\\mathrm{C}$) decreased in samples with higher Cu concentrations and found that the region tended to expand with increasing Cu concentration. In addition, the temperature dependence of the upper critical field ($H_\\mathrm{C2}$) of Cu-doped TaSe$_3$ was found to differ from that of pure TaSe$_3$.
