PURPOSE: Provided is an automobile battery relay which gives an embossing tool to a driving contact point and a ball holding tool to a plunger for raising contact performance in the driving contact point so that it improves contact power in a contact terminal. CONSTITUTION: In the automobile battery relay which contains a plunger(10), a driving contact point(11), a return spring(12), a fixed contact point(13), a battery switch(14) and a magnetizing coil(15), the automobile battery relay is characterized by forming multiple embossing(16) in the lower side of the driving contact point to point-contact to the fixed contact point, a groove(18) in the plunger, a ball(17) and a ball spring(19) in a wall side of a frame to contact to the contact terminal with keeping balancing contact state in which the ball is placed at the groove.
