A gas sensor (3) includes an insulating substrate (31), two electrodes (33, 35) formed thereon, and a sensing layer (37) formed on the insulating substrate and the electrodes. Each electrode defines a plurality of receptacles (332, 352) adjacent a surface thereof The sensing layer contains a plurality of sensing particles (372). A portion of the sensing particles is received in the receptacles. The sensing particles are physically divided into several connected parts by the receptacles, and accordingly are highly dispersed. Thereby, more spaces among the sensing particles are provided, for improving the sensitivity of the gas sensor.
