1. A rotation angle detector comprising:

  • a rotor core rotating with a rotary member of which a rotation angle is detected, said rotor core including a magnet generating a magnetic force;

    a non-contact type magnetic sensing element receiving the magnetic force of said magnet to detect the rotation angle of said rotary member; and

    a stator core supporting said non-contact type magnetic sensing element and forming a magnetic circuit with said rotor core, wherein;

    said stator core includes a first stator core portion, a second stator core portion and a non-magnetic plate, wherein said non-magnetic plate connects an end surface of said first stator core portion to an end surface of said second stator core portion; and

    said first stator core portion and said second stator core portion define a magnetic sensing gap having a predetermined width therebetween.
