Abstract
An electromagnetic relay includes a movable element, a movable yoke, a fixed yoke, a movable section, and a stopper. The movable element includes a movable contact point. The movable yoke is connected to the movable element to move together with the movable element. The movable section includes a movable core made of an inorganic magnetic material and a shaft made of an inorganic material. The fixed yoke is made of an inorganic magnetic material and disposed between the movable core and the movable yoke. The stopper protrudes from either one of the fixed yoke or the movable section toward the other to contact with the other when the movable section moves toward the fixed yoke. The stopper is integrally formed with the either one of the fixed yoke or the movable section.
