摘要： A magnetic core member, an antenna module, and a portable communication terminal having this, which have a configuration capable of satisfying enhancement of communication characteristics of antenna coils as well as their sufficient electromagnetic shielding function from a shield plate. A magnetic core member (4) is disposed between an antenna substrate having antenna coils (11), (12) formed therein and a conductive shield plate (3), and is formed by filling an insulating material (30) with a magnetic powder (31). The magnetic core member (4) has a two-layered structure including a first layer (4A) and a second layer (4B), thereby making a filling rate of the magnetic powder (31) in the first layer (4A) be lower than that of the magnetic powder (31) in the second layer (4B) so that a first surface (4a) on a side opposed to the antenna substrate (2) and a second surface (4b) on a side opposed to the shield plate (3) have magnetic properties different from each other.

摘要： To provide a magnetic powder production method, a magnetic sheet production method, and an antenna module production method that are capable of reducing a size of magnetic particles, achieving thinning and a low loss, and improving magnetic permeability without lowering it.At least two oxide-based magnetic materials are mixed, preliminarily calcined, and pulverized. The pulverized magnetic materials are typically formed into a paste by being dispersed in an organic solvent, and the magnetic materials are applied onto a film after being subjected to defoaming processing. Accordingly, a sheet-like magnetic material is formed. The sheet-like magnetic material is cut into predetermined sizes so as to be fragmented into particles, with the result that magnetic particles are formed.

摘要： A communication-capable electronic device is provided which includes a metallic housing (122) to accommodate electronic parts of the device, and a communication terminal (90) that makes communications with a communication-cable IC card (110) incorporating an antenna (115). The communication antenna (90) is located such that when the IC card is placed near the housing (122), the antenna (115) built in the IC card (110) faces, at a part thereof, a part of the communication terminal (90) while the rest of the antenna (115) of the IC Card (110) does not face the housing (122). Thus, it is possible to prevent the inductance in the antenna (115) of the IC card (110) from being reduced.
