Abstract
An electromagnetic relay includes a base, an electromagnet block fixed to the base, an armature which reciprocates when the electromagnet block is switched between an excitation state and a non-excitation state, and a card which slides in association with the movement of the armature. The base includes a rail portion which guides the card upon sliding, and the card includes a slide portion which slides along the rail portion. The rail portion includes a stopper portion which prevents disengagement of the slide portion from the rail portion.
