We present the results on the Coulomb dissociation of the neutron-halo-nucleus candidate {sup 19}C, which was studied by a kinematically complete measurement of the breakup of {sup 19}C on a Pb target into {sup 18}C and neutron at 67{center_dot}AMeV. A large E1 strength has been observed at the low excitation energy of around 1 MeV to follow the distribution characteristic of the direct Coulomb breakup for the 2s{sub 1/2}-dominant configuration of {sup 19}C halo wave function. The angular distribution of {sup 18}C+n center of mass system has led to the indirect determination of {sup 19}C one-neutron separation energy, with which the excitation energy spectrum is well reproduced.
