Zusammenfassung:	To obtain a capacitor for a power conversion device capable of sufficiently cooling a smoothing capacitor used in a power conversion device and suppressing electric vibration during a power conversion operation.SOLUTION: A capacitor for a power conversion device includes a cooler that molds a capacitor element and a magnetic material with resin and cools the capacitor element and the magnetic material, and the heat generated in the capacitor element during power conversion is cooled by the cooler, and the oscillating current flowing through the capacitor element is suppressed by the magnetic hysteresis characteristics of the magnetic material.SELECTED DRAWING: Figure 1 【課題】電力変換装置で使用される平滑コンデンサを十分に冷却すると共に電力変換動作の際の電気振動を抑制できる電力変換装置用コンデンサを得る。【解決手段】電力変換装置用コンデンサは、コンデンサ素子と磁性体とを樹脂でモールドし、これを冷却する冷却器を備え、電力変換の際にコンデンサ素子に発生する熱を冷却器で冷却すると共に、コンデンサ素子に流れる振動電流を磁性体の磁気ヒステリシス特性で抑制する。【選択図】図１
