[Problem] To provide a reformate production method and reformate production apparatus with which reformate can be obtained in high yields when producing reformate using supercritical water. [Solution] A reactor (1) is maintained at a temperature and pressure at or above the critical point of water, brings heavy oil and the supercritical water into contact, and while causing thermal cracking of said heavy oil to proceed, forms: a first phase from the heavy oil components obtained by thermal cracking of the heavy oil and supercritical water solubilized in said heavy oil components below; and a second phase from said supercritical water and light oil components extracted into said supercritical water above. A first mixed fluid is drawn out from said first phase from the lower part of said reaction unit so as to limit coke formation in said heavy oil components, while a second mixed fluid is drawn out from the second phase from the upper part of said reaction unit so as to limit gas formation from said light oil components. In a mixing unit (2), the heavy oil components of the first mixed fluid are mixed with the light oil components of the second mixed fluid to obtain the reformate.
