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.
Claims10
A battery-embedded device comprising:
- a multi-layer wiring substrate in which a wiring is buried;
- a coil fixed to the multi-layer wiring substrate;
- a battery fixed to the multi-layer wiring substrate;
- and
- a first temperature detecting element that is disposed on the multi-layer wiring substrate and configured to detect a temperature of the battery,
- wherein an occupancy rate of the wiring in a first region of the multi-layer wiring 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 multi-layer wiring substrate other than the first region.
