Abstract: An electromagnetic relay has a movable touch piece, a movable contact provided on the movable touch piece, and a fixed contact opposed to the movable contact. The movable touch piece is rotated by a movable iron piece that rotates based on magnetization and demagnetization of an electromagnet block, to make the movable contact come into contact with and separate from the fixed contact. Operation characteristics are made adjustable by a press-fitting amount at the time of press-fitting a fixed contact terminal provided with the fixed contact into a spool of the electromagnet block along a moving direction of the movable contact.
