To provide a scroll-type electric compressor which can be improved in operation efficiency.SOLUTION: In a scroll-type electric compressor, a pressure discharge path R for making a backpressure chamber and a motor chamber communicate with each other is arranged at a rotating shaft 60 and a balance weight 90. The pressure discharge path R has a flow-in port formed at the rotating shaft 60, and opened at the backpressure chamber, and a second flow-out port Ex2 as a flow-out port which is opened at a second side face 91c being a side of the balance weight 90 opposite to a rotation direction D1 of the rotating shaft 60.SELECTED DRAWING: Figure 2 【課題】スクロール型電動圧縮機の運転効率を向上できるスクロール型電動圧縮機を提供すること。【解決手段】スクロール型電動圧縮機において、回転軸６０及びバランスウェイト９０には、背圧室とモータ室とを連通する放圧経路Ｒが設けられている。放圧経路Ｒは、回転軸６０に設けられるとともに背圧室に開口した流入口と、バランスウェイト９０の回転軸６０の回転方向Ｄ１とは反対側の面である第２側面９１ｃに開口した流出口としての第２流出口Ｅｘ２とを有している。【選択図】図２
