An electric compressor includes a terminal structure. The terminal structure may include a busbar assembly electrically connected to an inverter and a terminal electrically connected to a motor part. The terminal structure may include at least one electrical connection member. Contact plates may be electrically connected to each end of the electric connection member. The busbar assembly for electrically connecting the terminal and the inverter device may include a plurality of busbars having a large surface area. When high current is applied to the electric compressor, as the surface area of respective members brought into contact with each other for electric connection increases, contact heat resistance decreases, which makes it possible to apply a high current without increasing the size of the terminal.
