PROBLEM TO BE SOLVED: To provide a mold clamping device and a method for controlling the mold clamping force capable of relaxing the effect on the mold clamping force due to the gap of two magnetic poles when generating the mold clamping force by using an electromagnet. SOLUTION: The mold clamping device generates the mold clamping force by an electromagnet, and the electromagnet is characterised by generating the rated or the maximum mold clamping force of the mold clamping device in the state in which the increasing rate of magnetic flux density to applied current becomes about 2% or lower comparing with the increasing rate when the magnetic flux density is less than 1 T.
