Abstract
A miniature surface-mount electronic component which can ensure sufficient impact resistance and vibration resistance especially in an application to a severe use environment such as a vehicle-mounted coil, by putting some contrivance into a method for fixing a coil in a molding process and a method for holding a core and terminals. A miniature surface-mount electronic component including a bar-shaped core 2 on which a winding wire 3 is wound, and metal plates 5, with an outer casing 7 made of an insulating resin molded, includes flanges 2b substantially quadrangular in section at both ends of the bar-shaped core 2, and vertical grooves a and b are provided on side surfaces of the flanges 2b of the bar-shaped core 2 as fixing portions for preventing positional displacement occurring when the outer casing 7 is molded.
