Abstract
A power supply unit of an inhalation device comprises: a power source unit capable of supplying power to a heating unit for heating at least one of a stick-type substrate and a flavor source; a sensor FPC having a stick detection sensor, an inhalation sensor, and a case temperature sensor mounted thereon or electrically connected thereto; and a case. A first wiring layer and a second wiring layer are stacked in the sensor FPC. In a case-facing region of the sensor FPC, a wiring area of signal wiring formed on the layer, out of the first wiring layer and the second wiring layer, on the side closer to the case is smaller than a wiring area of the signal wiring formed on the layer on the side further from the case.
