PROBLEM TO BE SOLVED: To provide an electromagnetic relay with excellent conductivity and an interceptive property, having a small size and capable of controlling three-phase currents of a three-phase motor and so on simultaneously. SOLUTION: An electromagnetic relay includes a stationary contact terminal assembly 114 having three columns placed in a line at equal intervals and a movable contact spring assembly 111 having three movable contacts 107. An armature 110 is rocked by an excitation current flowing through a coil assembly 103 so that a normally open contact portion is opened or closed. A flexible portion is functionally separated from a conductive path by forming a u-shaped slit in each of three branches of the movable contacts of a movable spring 108, A conductive plate 109 is joined with the conductive path to electrically connect the three movable contacts 107.
