Abstract: Provided are a rolling observation technique whereby the state of rolling on a rolling interface between a material to be processed and a roll can be observed easily and on site; a rolling state observation apparatus for observing the state of rolling at the rolling interface between a material to be processed and a roll during rolling of the material to be processed using two rolls, wherein the two rolls are constituted from a stationary fixed roll and a moving roll that rotates on its own axis while revolving around the fixed roll, and a device for observing the rolling state is provided to the fixed roll; and a rolling state observation apparatus comprising a revolution means for causing the moving roll to revolve around the fixed roll with the center axis of the fixed roll as the rotation center, and a rotation means for causing the moving roll to rotate on its own axis, the rolling state observation apparatus being configured so that the moving roll rotates on its own axis due to the revolution of the moving roll caused by the revolution means.
