Title: GAS SENSOR DEVICE AND METHOD OF MANUFACTURING SAME
Abstract:
[Problem] To provide a compact gas sensor device including a gas detecting unit containing a coil-shaped heater unit having restricted power consumption. [Solution] A package 15 includes a base 40 in which a recessed portion is formed, and the height from an uppermost portion to a lowermost portion of a cap 20 is at most equal to 5 mm. A first electrode to a third electrode 83 are fixed around the recessed portion 41, embedded in the base 20. A gas detecting element 60 includes a gas detecting unit containing a coil-shaped heater unit, and a plurality of metal lead wires which extend from the gas detecting unit to the first electrode to the third electrode 83. The gas detecting element 60 is fixed in a state in which the gas detecting unit, including the heater unit, is suspended by means of the plurality of lead wires in a space inside and above the recessed portion, in such a way that the gas detecting unit does not come into contact with the walls of the recessed portion.
