To obtain a surface mounting-type electronic component in which a fillet can be formed on the side face of an external terminal in a mounting operation even when a surface treatment is not executed to the side face of the external terminal as a cut face and to obtain its manufacturing method.

An external terminal 12 and an external terminal 13 are constituted of metal plates whose both sides are covered with metal films 21, 22. The hardness of the metal films 21, 22 is set so as to be softer than the hardness of the metal plates. Extension parts 23 in which the metal films 22 are extended by 1/3 or higher the plate thickness of the metal plates are formed on side faces 12a to 13b and end faces 12c, 13c of the external terminals 12, 13. The extension parts 23 are formed by drawing out the metal films 22 when they are cut from the side of a mounting face in order to form the external terminals 12, 13 from a blank.
