摘要： A coil component includes an insulating base body and a coil conductor arranged in the base body and having a winding portion extending around a coil axis. The insulating base body includes a magnetic body portion made of a magnetic material and a magnetic gap portion made of a low-permeability material having a lower relative permeability than the magnetic material. The magnetic gap portion is shaped like a ring when seen in a direction along the coil axis and arranged within the winding portion. The magnetic body portion includes a first region positioned within the winding portion, a second region positioned opposite the first region with respect to the magnetic gap portion in the direction along the coil axis, and a third region arranged within a through hole defined by an inner peripheral surface of the magnetic gap portion, where the third region connects together the first and second regions.

摘要： [Object] To provide an arithmetic device, an arithmetic method, and a gas detection system that are capable of easily correcting deterioration over time of a detection element.
[Solving Means] The arithmetic device includes a calculation unit. The calculation unit calculates a correction coefficient from a detection element that causes a resonant frequency change by adsorption of gas on the basis of a resonant frequency change amount associated with a humidity change of the detection element in a degraded state and a resonant frequency change amount associated with a humidity change of the detection element in an initial state that was acquired in advance, and corrects the resonant frequency change amount of the detection element in the degraded state by using the correction coefficient.-
