A wireless power transmission apparatus, according to various embodiments disclosed in the present document, comprises: a first coil including a first conductive wire area formed of an arrangement of conductive wires, and a first opening area surrounded by the first conductive wire area; a second coil including a second conductive wire area formed of an arrangement of conductive wires, and a second opening area surrounded by the second conductive wire area; a first overlapping area formed by overlapping a portion of the first conductive wire area with a portion of the second opening area; and a first shielding member disposed on at least a portion of the first overlapping area, wherein the first shielding member may be configured to at least partially block an electromagnetic field generated by the second coil interfering in the first conductive wire area. Various other embodiments are also possible. Un appareil de transmission d'énergie sans fil, selon divers modes de réalisation divulgués dans le présent document, comprend : une première bobine comportant une première zone de fils conducteurs formée d'un agencement de fils conducteurs, et une première zone d'ouverture entourée par la première zone de fils conducteurs ; une seconde bobine comportant une seconde zone de fils conducteurs formée d'un agencement de fils conducteurs, et une seconde zone d'ouverture entourée par la seconde zone de fils conducteurs ; une première zone de chevauchement formée par le chevauchement d'une partie de la première zone de fils conducteurs avec une partie de la seconde zone d'ouverture ; et un premier élément de blindage disposé sur au moins une partie de la première zone de chevauchement, le premier élément de blindage pouvant être conçu pour bloquer au moins partiellement un champ électromagnétique généré par la seconde bobine interférant dans la première zone de fils conducteurs. Divers autres modes de réalisation sont également possibles. 본 문서에 개시된 다양한 실시예에 따르면, 무선 전력 송신 장치는, 도선(conductive wire)의 배열로 이루어진 제1 도선 영역과, 상기 제1 도선 영역에 둘러싸인 제1 개구 영역을 포함하는 제1 코일, 도선의 배열로 이루어진 제2 도선 영역과, 상기 제2 도선 영역에 둘러싸인 제2 개구 영역을 포함하는 제2 코일, 상기 제1 도선 영역의 일부분이 상기 제2 개구 영역의 일부분과 중첩하여 형성된 제1 중첩 영역, 및 상기 제1 중첩 영역의 적어도 일부에 배치된 제1 차폐 부재를 포함하고, 상기 제1 차폐 부재는 상기 제2 코일에서 생성된 전자기장이 상기 제1 도선 영역에 간섭되는 것을 적어도 부분적으로 차단하도록 구성될 수 있다. 이외에도 다양한 실시예가 가능하다.
