Abstract

This invention provides a magnetic encoder which has a cover having a large shielding area, and is capable of suppressing the effect of external magnetic field on a hall element. The magnetic encoder has an encoder unit (10), which contains: a substrate (15) on which an IC chip (14) having a hall element is mounted, a housing (13) rotatably supporting a shaft (11) having a magnet piece (12) corresponding with an IC chip (14) provided on the substrate (15), a cover (18) fitted on the housing (13) to cover the substrate (15), a strand wire introducing member (19) for only allowing the strand wires (20a) of a cable (20) to pass, the strand wire introducing member (19) being held in between the cover (18) and housing (13), a connector (17) mounted on a surface opposite to the IC chip mounting surface of the substrate (15), the connector (17) having strand wires (20) of the cable (20) which is drawn through the strand wire drawing member (19), and a heat shrinkable tube (40) adapted to fix and hold the outer periphery of the strand wire introducing member (19) and the cable (20) in the state that the strand wire introducing unit (19) and the cable (20) contact with each other.
