We performed spectroscopic observations of Ellerman bombs (EBs) in an active region of NOAA 10705 at Hida Observatory on 2004 November 24. The photospheric velocity fields of EBs have for the first time been investigated spectroscopically. From the Doppler shifts of a Ti II absorption line (6559.576 Å) and a broad H$\alpha$ emission line, we derived the photospheric velocity and the lower chromosp...
