    • An object of the present invention is to facilitate welding connection of an enameled wire to a busbar to increase accuracy and reliability of the welding, and provide a high quality and highly reliable busbar connection structure and inverter-integrated electric compressor by reducing processes of welding operation. In a busbar connection structure for closely contacting, welding and connecting an enameled wire end portion (27A, 28A) of a coil onto an external connection bent surface (35) formed on a busbar (33), a through hole (36, 46) through which the end portion (27A, 28A) of the enameled wire (27, 28) passes is formed on the inside of a base portion of the bent surface (35) of the busbar (33), and the end portion (27A, 28A) of the enameled wire (27, 28) is passed through the through hole (36, 46), positioned onto a welding point (35A) of the bent surface (35), and welded and connected onto the bent surface (35).
