In the present invention, a sintering raw material contains: a pulverized product of a compression molded article obtained following a pulverization step (S112) in which a compression molded article, formed by compressing an aggregate of carbonized wood, is pulverized; and a powdered coke and/or anthracite. The apparent density of the compression molded article is ０．６ｇ／ｃｍ３. Dans la présente invention, une matière première de frittage contient : un produit pulvérisé d'un article moulé par compression obtenu après une étape de pulvérisation (S112) au cours de laquelle un article moulé par compression, formé par compression d'un agrégat de bois carbonisé, est pulvérisé ; et un coke en poudre et/ou de l'anthracite. La masse volumique apparente de l'article moulé par compression est de ０,６ｇ／ｃｍ３. 焼結原料に、木材炭化物の集合体を圧縮して成形した圧縮成形物を粉砕する粉砕工程（Ｓ１１２）を経て得られた圧縮成形物の粉砕物と、粉コークス及び無煙炭のうちの少なくともいずれか一方と、を含み、圧縮成形物は、見掛け密度が０．６ｇ／ｃｍ３以上である。
