Abstract

An electromagnetic relay includes a fixed contact, a fixed terminal, a coil, an iron core, and a spool. The fixed terminal includes a contact support portion on which the fixed contact is provided. The coil is disposed behind the fixed terminal. The iron core includes a shaft portion and a head portion. The spool includes a hole and a flange. The shaft portion is disposed in the hole. The flange includes a first front surface and a second front surface. The hole is open at the first front surface. The first front surface is disposed rearward of and facing the head portion. The second front surface is disposed rearward of and facing the contact support portion. The second front surface is spaced a predetermined distance rearward from the first front surface. The predetermined distance is greater than the thickness of the contact support portion in the front-rear direction.
