Abstract

Disclosed is an electronic component that can easily form a direction identification mark. Also disclosed is a method of producing the electronic component. A laminated body (12) is constituted by laminating a plurality of insulation layers, and has a mounting surface (S1) that is parallel to the z-axis. A directional coupler comprising a main line (ML) and a sub-line (SL) is embedded in the laminated body (12). A direction identification mark (MK) is disposed on the top surface (S2) of the laminated body (12), which is parallel to the mounting surface (S1), and is constituted by exposing a via-hole conductor section, which is formed by filling a via-hole disposed on the insulation layers with a conductor, from the top surface (S1).

Description

technical field [0001] The present invention relates to an electronic component and its manufacturing method, more specifically, to an electronic component having a mounting surface parallel to the stacking direction and its manufacturing method. Background technique [0002] As a conventional electronic component, for example, a directional coupler described in Patent Document 1 is known. In the directional coupler described in Patent Document 1, a stacked body formed by stacking dielectric layers is formed. External electrodes are provided on side surfaces located at both ends in the lamination direction of the laminate. When mounting the above-mentioned directional coupler on a circuit board, the surface of the laminate parallel to the lamination direction is used as the mounting surface. That is, the directional coupler is mounted on the circuit board so that the surface of the laminate parallel to the stacking direction faces the circuit board. [0003] However, in t...
