摘要： PROBLEM TO BE SOLVED: To solve such problems that a tablet cannot be formed when using an E-shaped tablet and reducing the shape thereof, because the shape of a tablet is complicated, that even if it is formed, the strength cannot be kept, and it is damaged in the way of manufacturing, that since the size of a coil is limited for keeping the strength, the characteristics degrade, and that when forming while holding the lead-out ends of a coil by means of a die, large burrs are generated in a core.SOLUTION: A surface mounting inductor includes a coil formed by winding a wire, and a core containing magnetic powder and incorporating the coil. The coil has lead-out ends exposed, respectively, to both side faces of the core. The lead-out ends of the coil are connected with an external electrode formed in the core.
摘要翻译：要解决的问题为了解决当使用E形片剂并且减小其形状时不能形成片剂的问题，由于片剂的形状复杂，即使形成，也不能保持强度，并且以制造方式被损坏，由于线圈尺寸受到限制以保持强度，所以特性劣化，并且当通过模具保持线圈的引出端形成时，会产生较大的毛刺在芯体中产生。解决方案：表面安装电感器包括通过缠绕线形成的线圈和包含磁粉并包含线圈的芯。线圈具有分别露出到芯的两个侧面的引出端。线圈的引出端与形成在芯中的外部电极连接。

The coil is formed by winding a wire so that the terminal is located on the outer periphery of the coil, and a plurality of layers having winding axes, shifted from each other, are formed. The coil exposes its side face to the side of the core, and exposes the lead-out ends to the side face adjoining the side of the core. The lead-out ends of the coil are connected with an external electrode formed in the core.

摘要： PROBLEM TO BE SOLVED: To provide a small surface-mounting inductor manufacturing method.SOLUTION: In a surface-mounting inductor manufacturing method according to the present invention, a sealing material is preliminary molded into a shape having a columnar projection at a peripheral edge of a plane shape to form a tablet. A flat wire is wound to form a coil. The coil is located on the tablet, and both ends of the coil are arranged on a molding die along an outside face of the columnar projection of the tablet. While both ends of the coil are sandwiched between the outside face of the columnar projection of the tablet and an inner wall of the molding die, the coil and the sealing material are integrated using a resin molding method or a powder compaction method, so as to form a core section. By polishing or cutting a surface of the core section except for a surface on which both ends of the coil are exposed, the core section is resized. An external electrode connected to a portion at which at least one part of both ends of the coil is provided on the surface of the core section.
