Abstract: A communication device includes a substrate, a magnetic sheet disposed above an upper surface of the substrate, a first coil disposed above an upper surface of the magnetic sheet, a second coil having a portion facing an edge surface of the substrate in a direction parallel with the upper surface of the substrate, and an electronic component disposed on the upper surface of the substrate. The electronic component is configured to generate noise. The magnetic sheet has a portion overlapping the second coil viewing from above. The electronic component is exposed from the magnetic sheet viewing from above. This communication device has a small size and prevents influence of noise generated by the electronic component.

Abstract: A battery-embedded device includes a substrate having a wiring, a coil fixed to the substrate, a battery fixed to the substrate, and a first temperature detecting element that is disposed on the substrate and configured to detect a temperature of the battery. An occupancy rate of the wiring in a first region of the substrate which is immediately below the first temperature detecting element is lower than an occupancy rate of the wiring in a second region of the substrate other than the first region.
