A tracheostomy tube that enables speech. The tube is provided with an inside tube portion to be set in a trachea, an outside tube portion connected to a ventilator, and a balloon provided on the outer circumference of the inside tube portion. The tube is designed to have a diameter in the range of 20 to 80%, and preferably 40 to 60%, of the diameter of the trachea. The balloon is connected to the inside tube portion so that the inside and outside of the balloon cannot communicate with each other and the inside tube portion has a hole for communicating the inside of the interior of the inside tube portion with the inside of the balloon.
