Summary:An electromagnetic relay is provided with: a contact switching unit formed by arranging at least two contact groups, each comprising a pair of contacts that can touch and separate, in parallel with each other and perpendicular to the touch/separation direction of the contacts; an electromagnet block that drives the contact switching unit to open and close the contacts; and an arc-extinguishing member comprising a connection member made from a magnetic material and formed by the connection, via a middle part, of protrusions that respectively protrude from both sides of the middle part in the direction of the parallel arrangement of the contact groups and between the contact groups, and also comprising permanent magnets respectively disposed at least on the opposing positions of the protrusions located on both sides of the middle part.
