Investigation on the methane emission from the surface of waste landfill that contains industrial waste was executed. . Twenty-four out of 45 points in summer and 20 out of 42 points in winter showed no methane flux. Influx of methane was observed in a few points, and flux rate ranged from -0.29 to 370 ml/m<sup>2</sup>/min in summer and from -0.50 to 109 ml/m<sup>2</sup>/min in winter. Ground temperature and methane flux showed certain correlation. Whole methane emission was estimated based on the correlation with ground temperature and the distribution of ground temperature. Estimated methane emissions from the whole landfill estimated were 0.57 m<sup>3</sup>/hr and 0.039 m<sup>3</sup>/hr in summer and winter, respectively.
