Abstract
Provided is an electromagnetic relay that is reduced in size and has great flexibility in designing. For this purpose, when a predetermined time has passed after generation of an arc at least either between a movable contact and a fixed contact or between a movable contact and a fixed contact, an arc generated between the movable contact and the fixed contact is extended by a magnetic field generation unit to be longer than an arc generated between the movable contact and the fixed contact.
