Electromagnetic relay and electromagnetic device

The electromagnetic relay includes a contact unit, an electromagnet, an armature unit, and a base. The contact unit includes a fixed contact and a movable spring including a movable contact. The armature unit is movable in accordance with excitation of the electromagnet to allow the movable contact to move between a closed position in contact with the fixed contact and an open position away from the fixed contact. The base holds the contact unit and the electromagnet on a certain surface side. The movable contact is placed between the base and the fixed contact in an arrangement direction in which the base and the electromagnet are arranged. The armature unit includes a press part which causes movement of the movable contact by applying a pressing force to a certain surface facing the fixed contact, of the movable spring.
