An electromagnetic induction position detection sensor includes a plurality of loop coils, each being an N-turn loop coil formed by winding a conductor N times (N is an integer equal to or greater than 2), and each coil turn having long side portions that are separated by a predetermined width and that are parallel to each other. The loop coils are arranged at predetermined intervals in a predetermined direction intersecting the long side portions of the loop coils. The width of at least one of the N turns of the Mth loop coil from the edge portion of the sensor in the predetermined direction (M is an integer equal to or greater than 2) is larger than the predetermined width, with the long side portion of this turn of the Mth loop coil arranged more outward than the long side portions of the other turns of the Mth loop coil.
