Problems solved by technology

Therefore, there is a problem that external terminals are required to span multiple surfaces of the die coil, and additional external terminals are formed on other than the mounting surface.
In addition, since the process of forming external terminals on multiple surfaces is required, there is a problem that manufacturing is laborious.

Abstract

The present invention provides an electronic component having no additional external terminals other than a mounting surface and a method of manufacturing the same. The electronic component is constituted as follows: at least one coil having a winding portion and lead-out ends positioned at both ends, and a magnetic molded body having the coil built in and having a mounting surface, the lead-out ends are drawn toward the mounting surface, and the lead-out The end surface of the end portion is arranged on the same plane as the mounting surface.

Description

technical field [0001] The present invention relates to an electronic component and a manufacturing method thereof. Background technique [0002] Conventionally, electronic components in which coils are sealed with magnetic sheets have been widely used. In the die coil described in Patent Document 1, a plurality of coils are sandwiched between flat magnetic bodies, and the coils are further pressurized to seal the coils. Then, the magnetic body including the coil is cut into a predetermined shape to obtain a die coil. Both ends of the coil are drawn from the sides of the die coil to be connected to external terminals. Also, the external terminal is formed across the side surface and the mounting surface of the die coil. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2011-3761 [0004] In the die coil disclosed in Patent Document 1, the surfaces at both ends of the lead-out coil are different from the mounting surfaces. Therefore, there is a problem that an ex...
