Abstract
A magnetic encoder is provided which can prevent a magnetized member from being separated from a fixed member to which the magnetized member is fixed under a severe temperature environment. The encoder includes a fixed member which is fixed to a rotating member and a magnetized member which is attached to the fixed member. The magnetized member, which is molded by mixing a magnetic powder in a resin, is bonded to the fixed member with a silicone resin based adhesive, and a thickness of an adhesive layer of the silicone resin based adhesive is 50 μm or more and 100 μm or less.
