    摘要： An electrochemical element comprises a solid electrolyte (1,2) and a pair of electrodes (4,6) provided in contact with the solid electrolyte. To achieve good operation at low temperature, and good response and durability, the solid electrolyte consists of a dense solid electrolyte body (1) and a porous solid electrolyte layer (2). At least one of the electrodes is a cermet electrode (4) which is formed in contact with the porous solid electrolyte layer (2), being fired simultaneously with the dense solid electrolyte body (1) and the porous solid electrolyte layer (2). The first electrode may be exposed, through a diffusion-resisting means, to a space for a gas to be measured.
