A centrifugal counter-flow liquid container contactor in which a light liquid and a heavy liquid are introduced into a rotary body fixed to a rotary shaft from the outer peripheral portion and the inner peripheral portion of the rotary body, respectively, so that the light liquid and heavy liquid make counter-flow contact with each other and, after the contact, the light liquid and heavy liquid are discharged from the inner peripheral portion and outer peripheral portion of the rotary body. Disc-shaped partition plates are disposed at both sides of radially extending pipes within the rotary body such as a light liquid introduction pipe, heavy liquid discharging pipe and so forth inserted into the rotary body, so as to separate these radial pipes from the region where the light and heavy liquids are mixed with each other.
