摘要： A wearable electronic device according to an embodiment of the disclosure may include a housing, a circuit board assembly disposed inside the housing, and/or a coil assembly disposed around the circuit board assembly. The circuit board assembly may include a first circuit board layer and/or at least one sensor including a plurality of electric elements (e.g., photoelectric conversion elements). The first circuit board layer may include a first conductive area on which at least one conductive pattern is formed and a first non-conductive area formed around the first conductive area. The plurality of electric elements may be disposed along a periphery of the first circuit board layer. The first conductive area may include an outer edge area disposed around each of the plurality of electric elements. The first non-conductive area may include at least one slit area disposed in the outer edge area.
