A magnetic response section provided by a scale of a magnetic linear sensor is configured so that changes in magnetic influence on a magnetic detection head appear alternately and repeatedly every first pitch in a displacement detection direction. The magnetic detection head is provided on one side of the scale in the first direction, which is a direction perpendicular to the displacement detection direction, and provided with a base substrate section and a plurality of signal output sections. The signal output sections are arranged on an insulating plate and in the displacement detection direction at a second pitch based on a first pitch. The first conductive pattern and the second conductive pattern included by each of the signal output sections are formed to arrange coil elements side by side in an elongated area in a second direction orthogonal to both the displacement detection direction and the first direction.
