The present invention addresses the problem of providing a hemodialysis solid agent A, in which acetic acid odor can be reduced, in which solidification due to storage, decomposition of glucose when made to coexist with glucose, and an increase in pH when dissolved in water can be suppressed, and which has excellent storage stability. The problem can be solved by a hemodialysis solid agent A which substantially contains only one among magnesium chloride and potassium chloride, and which includes a first fraction composed of granules containing calcium chloride and a second fraction containing acetic acid and acetate.就本案課題而言，本發明之目的是提供一種固體狀血液透析用A劑，該血液透析用A劑能夠降低醋酸味(odor of acetic acid)，且進一步能夠抑制保存所致之固化、使與葡萄糖共存之際葡萄糖的分解、及溶解於水時的pH上升，且保存穩定性優良。 本案之解決手段是藉由使一種固體狀血液透析用A劑包含第1組分與第2組分能夠解決前述課題；其中，該第1組分是以實質上僅包含氯化鎂及氯化鉀之其一，且包含氯化鈣的造粒物所構成，該第2組分包含醋酸及醋酸鹽。
