Abstract: A heater device includes a light transmissive film heater configured to apply to an optical window that is arranged adjacent to a sensor unit for detecting light and includes a detection surface having a light transmitting property, and including a heating portion heating the optical window, and a heat generating portion configured to generate heat in a predetermined region. The light transmissive film heater includes a first electrode arranged radially outside about a center line of the detection surface in the heating portion, a second electrode arranged in the heating portion so as to interpose the detection surface from both sides together with the first electrode, and a first heat generation region that generates heat according to a potential difference between the first electrode and the second electrode generated by energization from the first electrode to the second electrode via the heating portion.

Abstract: A film heater includes a transparent conductive film and first and second electrodes. The transparent conductive film includes a heat generating portion that generates heat when energized by the first and second electrodes. An outer edge of the heat generating portion has a short side, a long side, and first and second oblique sides. The first and second electrodes include a plurality of first and second connection portions corresponding to a plurality of first and second ports, respectively. A plurality of first and second current suppression portions is disposed to suppress flow of the current between the inside and outside of the heat generating portion through a region between the plurality of first and second ports, respectively. For each of some or all of the plurality of first ports, the current flows through the heat generating portion between the first port and at least two second ports.

Abstract: An ammonia detector includes a solid electrolyte body, a detection electrode, and a reference electrode. The solid electrolyte body includes a measured gas facing surface, which comes into contact with a measured gas, and a reference gas facing surface, which comes into contact with a reference gas. The detection electrode is formed on the measured gas facing surface of the solid electrolyte body. The reference electrode is formed on the reference gas facing surface of the solid electrolyte body. The detection electrode contains at least alumina and 50% or more by mass of Pd.
