Abstract: A speaking valve which is applied to a respiration opening of a tracheostomy tube comprises: a main body portion which has a passage portion communicating with the respiration opening; a balloon which makes a motion between an opened state for opening the passage portion of the main body portion and a closed state for closing the passage portion; a syringe which is provided away from the main body portion and accepts a pushing operation to a plunger by a patient; and a coupling tube which couples the syringe and the balloon with each other and makes the balloon in a shrink state transform to a bloat state by the operation to the syringe, so that the motion from the opened state to the closed state is made.
