Abstract
An electromagnetic relay includes a base, an electromagnetic block disposed on an upper surface of the base, a movable iron piece that rotates based on excitation/non-excitation of the electromagnetic block, a movable contact piece that rotates integrally with the movable iron piece, a movable contact fixed to a free end of the movable contact piece, a fixed contact disposed so as to come into or out of contact with the movable contact in association with rotation of the movable contact piece, and a magnetic field generation unit disposed so as to attract an arc generated between the movable contact and the fixed contact in a direction that, as seen from the fixed contact, is opposite to the movable contact and the base.
