A new near detector, Scintillator Bar (SciBar), for the K2K long-baseline neutrino oscillation experiment was installed to improve the measurement of the neutrino energy spectrum and to study neutrino interactions in the energy region around 1 GeV. SciBar is a 'fully active' tracking detector with fine segmentation consisting of plastic scintillator bars. The detector was constructed in the summer of 2003 and is taking data since October 2003. The basic design and initial performance are presented.
