We report on a new type of photonic crystal laser structure, nano stepping-stones (NSSs), composed of a linear (or one-dimensional) chain of equally spaced discrete InAsP/InP multiple-quantum-well nanorods bonded onto a fused silica substrate. When optically pumped, the NSSs lased in a single band-edge mode with the polarization perpendicular to the direction along the NSSs. The cavity quality factor estimated from numerical simulations exceeded 10^{4}, and the measured threshold pump power density was as small as 285 W/cm<sup>2</sup>. Detailed emission spectra analyses confirmed that the lasing occurred at a photonic band-edge.
