Abstract

An electromagnetic relay includes a first fixed terminal, a second fixed terminal, a housing, a coil, and a spool. The second fixed terminal is disposed in front of the first fixed terminal and faces the first fixed terminal. The housing includes a side surface that laterally covers the first fixed terminal and the second fixed terminal. The coil is wound around the spool. The spool includes a support portion and a lateral wall portion. The support portion supports the first fixed terminal. The lateral wall portion extends from the support portion and is disposed between the first fixed terminal and the side surface of the housing in the left-right direction. The front end of the lateral wall portion is located between the first fixed terminal and the second fixed terminal in the front-rear direction.
