A mold for horizontally and continuously casting molten metal into a cast metal strand, which is horizontally connected, through a front nozzle, a feed nozzle and a break ring to an opening in a lower portion of a side wall of a tundish for a horizontal type continuous casting machine. Molten metal received in the tundish is intermittently and continuously withdrawn into a cast metal strand in the horizontal direction through the mold in a plurality of cycles each comprising one pull and one push. The transverse sectional area of the inner bore of the mold at the inlet end portion thereof becomes gradually larger from the inlet end of the mold toward the middle portion thereof over a prescribed distance (l), and the inner bore of the mold has substantially the same transverse sectional area for the remaining portion other than the inlet portion of the mold over the above-mentioned prescribed distance (l).
