<p>A gas sensor element (2) having a laminar structure including first and second solid electrolyte layers (4a, 4c) and a solid electrolyte spacer layer (4b) which are laminated on each other, with the spacer layer being interposed between the first and second solid electrolyte layers, the laminar structure having a buffer space (8), a first space (10) and a second space (12) which are formed between the first and second solid electrolyte layers, the laminar structure further having a gas inlet (16) through which the external measurement gas is introduced into the buffer space, a first diffusion controlling passage (20) through which the external measurement gas is introduced into the buffer space from the gas inlet, a second diffusion controlling passage (24) through which an atmosphere in the buffer space is introduced into the first space, a third diffusion controlling passage (32) through which an atmosphere in the first space is introduced into the second space.</p> |
