A mixing and degassing apparatus includes: a supporting member 14; a rotating base 16 supported on the supporting member so as to be rotatable on a first rotational axis Y1; a first rotating mechanism 18 for rotating the rotating base on the first rotational axis; a container 20 which is fixed to a peripheral portion of the rotating base and which is rotatable with the rotating base around the first rotational axis; a shearing stress applying member 40 having a shearing stress applying portion 40a which is arranged in the vicinity of a maximum centrifugal force applying region on the inner wall surface of the container and which is rotatable on a second rotational axis Y2; and a second rotating mechanism 46 for rotating the shearing stress applying portion of the shearing stress applying member on the second rotational axis to apply a shearing stress to a material to be treated in the container, wherein if the rotating base rotates on its own axis to revolve the container, the shearing stress applying portion rotates on its own axis while moving along the trajectory of revolution of the container, so that a shearing stress is applied to the material in the container to mix and degas the material.
