Abstract
To provide an electromagnetic relay having a reduced size, high conductivity, a high insulating performance between two fixed contact terminals and between each of the fixed contact terminals and backstop, a small number of factors causing a failure, and high reliability of electric contact.An electromagnetic relay has an electromagnetic block provided with a movable contact spring 14 swung by current flowing in a coil, two fixed contact terminals 22 and 22′ each having a fixed contact, a backstop 23 having two movable contact abutment portions, and a base block 2 for retaining the above components. The base block 2 has a base portion 20 having substantially a rectangular shape, fixed contact terminal retaining portions 21 and 21′ extending vertically from two opposing sides of the rectangle so as to retain the two fixed contact terminals, and a backstop retaining portion 24 extending vertically from the center portion of one of the remaining two opposing sides of the rectangle.
