PROBLEM TO BE SOLVED: To provide a pressurizing device for end face polishing of a minute work including controllability for the pressing force of the end face of a ferule to a polishing sheet and preventing flaw generation on the ferule end face by setting low the pressing force to the ferule end face particularly at the time of starting the polishing. SOLUTION: An end face polishing device is composed of a lever 10 on which a jig board 50 for fixation of a ferule is installed, a pressurizing part 20 to lower the lever 10 and press the end face of the ferule 5 fixed to the jig board 50 with a specified pressure onto a polishing sheet which makes elastic deformation, and a pressure control part 40 to control the pressing force for the ferule end face to the polishing sheet by the pressurizing part 20.
