Zusammenfassung:	To provide a technique for preventing dew condensation inside a housing of an inverter device.SOLUTION: An inverter device 1 comprises: a housing 6 that houses a power electronic element and an electrolytic capacitor; an opening formed in the housing 6; a thermal insulator 9 arranged along a circumference of the opening; and a water jacket 8 that has a cooling walter inflow pipe 81, an exhaust pipe 82 and a body part 85, with a first surface of the body part 85 being arranged via the thermal insulator 9 so as to block the opening from outside of the housing 6. The power electronic element is attached to the first surface of the body part 85, and the electrolytic capacitor is attached to an inside of the housing 6 and is in contact with an inner surface of the housing 6.SELECTED DRAWING: Figure 1 【課題】インバータ装置の筐体内部での結露を防止する技術を提供する。【解決手段】インバータ装置１において、パワー電子素子及び電解コンデンサを収納する筐体６と、筐体６に形成された開口部と、開口部の周囲に沿って配置された熱的インシュレータ９と、冷却水の流入パイプ８１及び排出パイプ８２とボディ部８５を有し、ボディ部８５の第一の面が、熱的インシュレータ９を介して、筐体６の外側から開口部を塞いで配置されたウォータジャケット８と、を備える。パワー電子素子は、ボディ部８５の第一の面に取付けられ、電解コンデンサは、筐体６の内部に取付けられ、筐体６の内面に接触している。【選択図】図１
