Document Type and Number:
WIPO Patent Application WO/2016/084811
Kind Code:

Abstract:
Provided is an electromagnetic actuator which uses magnets as a movable element, wherein a variance in adhesive strength is eliminated when the magnets and another metal body are joined via an adhesive, and an electromagnetic actuator which is capable of stable operation is produced at high yield. The present invention includes a movable element 2 provided with magnets 11, 12, 13 and a coil 3 for applying a drive force to the magnets 11, 12, 13. The movable element 2 is provided with a metal body (weight 20) that is joined to the magnets 11, 12, 13 and operates integrally with the magnets 11, 12, 13. The magnets 11, 12, 13 and the metal body (weight 20) are all covered with a plating film, with an organic coating being formed on the plating film, and are joined to one another via an adhesive applied over the organic coating.
