Claims (1)
が対峙して設けられ、これらの両素子の間を熱遮
蔽する熱遮蔽体とこの熱遮蔽体と前記両素子を覆
い、前記ベースに取り付けられるキヤツプとを備
えたガスセンサにおいて、キヤツプは、円注体を
軸方向に２つ割りにした半円注形状で半円形頂面
、側周曲面および側周平面が金属製網で形成され
半円形底面が開口された中空半円柱形体を２個そ
の側周平面を密着して一体としたものよりなり、
前記密着された中空半円柱形体の側周平面を熱遮
蔽体としたことを特徴とするガスセンサ。 A gas detection element and a temperature compensation element are provided facing each other on an insulating base, a heat shield for thermally shielding between these two elements, and a cap that covers the heat shield and both elements and is attached to the base. In the gas sensor equipped with the above, the cap has a semicircular shape in which the circular injection body is divided into two in the axial direction, and the semicircular top surface, side circumferential curved surface, and side circumferential plane are formed of metal mesh, and the semicircular bottom surface is formed of a metal mesh. Consisting of two hollow semi-cylindrical bodies with an opening, with their side circumferential planes brought into close contact with each other,
A gas sensor characterized in that a side peripheral plane of the hollow semi-cylindrical body that is in close contact with each other serves as a heat shield.
