PROBLEM TO BE SOLVED: To provide a low-cost liquid anesthetic vaporizer, capable of improving precision in anesthetic gas concentration, and easily changing the kind of liquid anesthetic by means of a single device. SOLUTION: The liquid anesthetic is supplied by a roller tubing pump into a gas passage in which anesthetic reference gas flows in from an inlet, and anesthetic gas flows out from an outlet, so that suction and discharge of the liquid anesthetic can be simultaneously performed, and that precision in anesthetic gas concentration is improved. By controlling rotation speed of a drive motor of the roller tubing pump based on the kind of liquid anesthetic selected in an anesthetic selection part, the kind of the liquid anesthetic can be easily changed.
