[Object] To provide a rolling apparatus that enables an operator to recognize the rolling status such as the behavior of the steel sheet entering the rolling stand and enables a stable rolling process. [Solution] A rolling apparatusincludes a plurality of rolling standseach including a pair of rolling mills, and an imaging unitprovided between adjacent rolling standsA andB, the imaging unitbeing configured to image a steel sheetentering a pair of rolling millsB of the rolling standB from an upstream side of the rolling standA located on a downstream side in a rolling direction. The imaging unitis disposed so as to satisfy the following equation (1), on the upstream side in the rolling direction Z of the rolling standB, in a central portion in the width direction of the steel sheet in an area P in which the steel sheetis able to be conveyed:2&#xd7;&#xd7;tan(&#x3b1;/2)&#x3e;&#x2003;&#x2003;(1)wherein L represents a distance in the rolling direction between the rolling standB located on the downstream side in the rolling direction and the imaging unit, &#x3b1; represents a horizontal viewing angle of the imaging unit, and Wrepresents a maximum width of the steel sheet
