To survey the present qualities of the molded and to present the base line of qualities in manufacture, the charcoal collected at 27 makers through the nation were examined. The molded charcoal examined in this paper, which is made by carbonization and molding of sawdusts from wood industries, is widely used to kindle holed-coal-briquette. The holed-coal-briquette is utilized in cooking and heating as primary energy source of ordinary households in this country. The average qualities of molded charcoal was as follows; ash content 13.95$\%$, weight 184.6g, density 0.47, time of kindling holed-coal-briquette 65.4 min., calorie 5,790 kcal/kg. The ten makers produced inferior qualities, that was 37 per cent of the 27 makers examined. The base line of qualities of molded charcoal was defined as follows; ash content below 17$\%$, weight above 175 g, falling strength above 300 mm, calorie above 5,500 kcal/kg.
