Provided is a vaporizer that can reduce ripples, particles, and a carbon content of a film and can supply a raw material capable of forming a film having a desired composition. Moreover, a vaporizer is obtained that sufficient vaporization can be performed without heating more than necessary and temperature management can be facilitated. A vaporizer includes a vaporizer main body (3) into which a carrier gas having a film forming liquid material dispersed is introduced and a heater main body (4) disposed in the vaporizer main body (3). The shape of the inlet portion of the heater main body is in a cone.
