Abstract

The present invention discloses a noncontact power-transmission coil, portable terminal and terminal charging device, planar coil magnetic layer formation device, and magnetic layer formation method. The noncontact power-transmission coil includes a planar coil and a magnetic layer. The planar coil is formed by winding a linear conductor in a spiral shape substantially in a single plane. The magnetic layer is formed by applying a liquid-form magnetic solution in which magnetic particles are mixed with a binder solvent, so as to cover one planar portion of the planar coil and a side-face portion of the planar coil.

Description

technical field [0001] The present invention relates to a non-contact power-transmission coil for charging a rechargeable battery contained in a small-sized, thin portable terminal such as a mobile phone unit using electromagnetic induction. Power transfer in contactless mode. The present invention also relates to a portable terminal and a terminal charging device including such a non-contact power transmission coil, and a magnetic layer forming method and a magnetic layer forming device for forming a magnetic layer in a planar coil of such a non-contact power transmission coil. Background technique [0002] Systems have been known in the past in which charging power for charging, for example, a rechargeable battery included in a portable terminal is transmitted by electromagnetic induction using a non-contact power transmission coil. [0003] Furthermore, Japanese Unexamined Patent Application Publication No. 2006-42519 ( figure 2 and FIG. 3 ) disclose a planar coil as a ...
