A position detection apparatus is provided, which includes a plurality of position detection systems such as an electromagnetic-type position detection system and a capacitive-type position detection system. The apparatus is configured to select a transmission conductor among a plurality of transmission conductors in a first position detection system, and to select a reception conductor among a plurality of reception conductors in a second position detection system, so as to increase the spatial distance between the selected transmission conductor in the first position detection system and the selected reception conductor in the second position detection system as much as possible, to thereby reduce interference. Further, a relationship of frequency interleave may be provided between a transmission signal to be supplied to the transmission conductor in the first position detection system and another transmission signal to be supplied to the transmission conductor in the second position detection system.
