PROBLEM TO BE SOLVED: To provide a drug vaporizer allowing easy replacement of a core material.SOLUTION: The drug vaporizer 1 includes: a container 2 for accommodating a liquid drug inside a core material 3 having a sucking portion 30 and a vaporizing portion 31 and a core material holding frame 4 for holding the core material 3. The core material holding frame 4 pulls up the vaporizing portion 31 to the outside of the container 2, thereby vaporizing the drug sucked by the sucking portion 30 to the outside of the container 2 through the vaporizing portion 31. The core material holding frame 4 includes: a pair of side frame members 40, 40 and engaging protrusions 48 formed on the lower ends of the side frame members 40 and retaining the core material holding frame 4 by engaging with the protrusions 25 in the container 2. The vaporizing portion 31 is held between the side frame members 40. The side frame members 40 can detachably attach the core material 3 by elastically swinging in an opposite direction to each other on the upper end as a fulcrum, and opening/closing members 44 for swinging the side frame members 40 are provided on the upper end of the side frame members 40.
