The present invention relates to a modularized vaporizer, which enables a fuel module, a heating module, or a vaporizing module to be coupled and separated, in a drawer manner, to and from a body portion housing since a fuel module chamber, a heating module chamber, or a vaporizing module chamber is provided in the body portion housing. The modularized vaporizer reduces the carbonization of fuel or an absorbent member since the fuel or a surface of the absorbent member is uniformly heated (irradiation) by heating energy (light, beam, or heat) emitted (irradiation) from a heating member of the heating module.
