To provide a production method of charcoal, enabling the charcoal to have increased strength.SOLUTION: A production method of charcoal comprises raising temperature of wood to 700°C to 1200°C to carbonize the wood while giving tar vapor to the wood. In the method, the raising temperature of the wood to 800°C enables the charcoal to be produced so that the charcoal has an apparent specific gravity of 0.55 g/cm3 or more, the raising temperature of the wood to 1000°C enables the charcoal to be produced so that the charcoal has the apparent specific gravity of 0.48 g/cm3 or more, and the raising temperature of the wood to 1100°C enables the charcoal to be produced so that the charcoal has the apparent specific gravity of 0.45 g/cm3 or more.SELECTED DRAWING: Figure 6 【課題】 木炭の強度を向上させることができる木炭の製造方法を提供する。【解決手段】 木材にタール蒸気を供給しながら、木材を７００℃以上１２００℃以下の温度まで昇温して炭化させる。ここで、木材を８００℃まで昇温し、見かけ比重が０．５５ｇ／ｃｍ３以上の木炭を製造することができる。また、木材を１０００℃まで昇温し、見かけ比重が０．４８ｇ／ｃｍ３以上の木炭を製造することができる。さらに、木材を１１００℃まで昇温し、見かけ比重が０．４５ｇ／ｃｍ３以上の木炭を製造することができる。【選択図】 図６
