To provide a magnetic line-type position-angle detecting device capable of detecting an absolute position on a non-contact basis and with high resolution and inexpensive construction, the magnetic line-type position-angle detecting device includes a magnetic line sensor 1 having a plurality of magnetic sensor elements 1 a arranged in line, and a magnetic generating element 2 confronting the magnetic line sensor and movable in a direction conforming to the line of the magnetic sensor elements 1 a. The magnetic sensor elements 1 a of the magnetic line sensor 1 are sequentially selected by a scanning circuit 3 , a signal from the selected sensor element 1 a is processed into a digital signal through an amplifier 4 , and an analog-to-digital converting circuit 5 . By a calculation processing circuit 6 , a distribution of magnetic fields applied to the magnetic line sensor 1 are measured to calculate the position and/or angle of the magnetic generating element 2.
