A heat equalizer includes a container structure having a heating block in which a working fluid is held for heating and vaporizing a material to be heated, a heater placed at the bottom of the container structure, and a material feed pipe allowing the outside and the inside of the container structure to communicate with each other. In the heating block, as a flow path in which the material to be heated flows, a main header pipe connected to the material feed pipe and extending in the horizontally, and a riser pipe branching from the main header pipe and extending vertically are formed. As a condensation path in which the working fluid is cooled and condensed, condensation holes formed respectively on the opposite sides of the riser pipe and extending horizontally, and a condensation pit formed under the riser pipe are formed. Between the condensation holes and the condensation pit, the main header pipe is placed.
