Summary:PROBLEM TO BE SOLVED: To provide a magnetic sheet material having a high mechanical strength even with hard magnetic powder and a very small resin addition amount.SOLUTION: A thin plate-like powder compact of 1.0 mm or less in thickness comprises soft magnetic powder and a resin. The soft magnetic powder includes soft magnetic powder A having an aspect ratio of 1.5-2.5 and a Vickers hardness of 300-500 HV, and soft magnetic powder B having a Vickers hardness of 70-150 HV; the soft magnetic powder A accounts for 30-70 mass%.SELECTED DRAWING: None 【課題】極少量の樹脂添加量でありながら硬質な磁性粉を用いても高い機械的強度を有する磁気シート材を提供する。【解決手段】軟磁性粉と樹脂を含む厚み１．０ｍｍ以下の薄板状圧粉成形体であり、アスペクト比が１．５〜２．５、ビッカース硬さが３００〜５００ＨＶの軟磁性粉Ａと、ビッカース硬さが７０〜１５０ＨＶである軟磁性粉Ｂとを含み、軟磁性粉Ａの割合が３０〜７０質量％である。【選択図】なし
