PROBLEM TO BE SOLVED: To provide a lens pressing tool capable of reducing deformation amount of a lens material at the time of blocking and making pressing force of the lens material constant. SOLUTION: This lens pressing tool is provided with a main body 20 and pressing parts 30 provided in the main body 20 to press the lens material 3 to a holding tool 2 side at three portions away from a lens center and arranged along a lens peripheral direction. Even if the lens material 3 is going to float when a fixing material is made to flow into a space between the holding tool 2 and the lens material 3, the lens material 3 can be suppressed by equal force by the three pressing parts 30.
