PURPOSE: A beam having a corrugated web and a composite beam using the beam are provided to make possible the lengthening of a steel beam by increasing the length of a steel beam and reducing the unit weight. CONSTITUTION: A composite beam comprises an upper flange, a lower flange(20), and a corrugated web(100). An aspect ratio of the web is 150~300. The web is composed of a left plate(110), a rightward inclined plate(120), a right plate(130), and a leftward inclined plate(140). The left plate is mounted to be inclined leftward more than the central line of the upper flange and the lower flange. The rightward inclined plate is mounted extendedly to be inclined rightward from the end of the left plate. The right plate is mounted to be inclined rightward more than the central line of the upper flange and the lower flange and is longitudinally extended from the end of the rightward inclined plate. The leftward inclined plate is mounted extendedly to be inclined rightward from the end of the left plate.
