The practice sword is configured such that the sword hilt body and the blade portion have a vinyl chloride pipe as a common core. The blade portion is formed by surrounding the outer surface of the common core vinyl chloride pipe with styrene foam, arranging an elastic cushioning material on a distal surface thereof, and accommodating the styrene foam and the vinyl chloride pipe in a thin and long thick cloth bag. The sword hilt body is formed by abutting top and bottom rod-like pieces of wood against the top and bottom peripheral surfaces of the common core and winding a string around the surfaces of the top and bottom rod-like pieces of wood.
