A foldable position detection sensor operable by electromagnetic induction coupling is configured to alleviate the problem of the levels of electromagnetic coupling with an electronic pen locally changing at a bending portion of the sensor. The position detection sensor includes a digitizer that includes an electrode configured to couple with a position indicator by electromagnetic induction coupling. The position detection sensor includes multiple electromagnetic sheets disposed to cover a surface of the digitizer opposite to an input surface thereof for receiving input form the position indicator. The multiple electromagnetic sheets are spaced apart from one another along the surface of the digitizer at a bending location where the digitizer is bent. The electromagnetic sheets are configured such that when the digitizer is in an unfolded state the electromagnetic sheets overlap with one another at the bending location in a direction perpendicular to the input surface of the digitizer.
