A position detection apparatus includes a position pointer having a coil and a sensor unit for detecting the position of the position pointer. The sensor unit has a sensor board including a plurality of loop coils juxtaposed and extending in a predetermined direction, and the sensor unit detects a signal generated in the loop coils by electromagnetic induction between the coil of the position pointer and the loop coils, to thereby detect the position of the position pointer. The sensor unit further includes a shield member disposed on the sensor board remotely from the position pointer for reducing noise, and a magnetic path sheet formed from a plurality of magnetic path members of a substantially rectangular shape having a higher magnetic permeability than that of the shield member and disposed between the sensor board and the shield member. The magnetic path members have mutually contacting portions disposed in an inclined relationship by a predetermined angle relative to said predetermined direction of the sensor board.
