ELECTRIC CIRCUIT DEVICE AND METHOD FOR MANUFACTURING ELECTRIC CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric circuit device capable of securing the durability of a connection part while reducing thermal influences on a periphery in the case of connecting a DC terminal to a connection terminal part.SOLUTION: A power electric circuit includes: a power module 300 having a DC positive electrode branch terminal 315D and a DC negative electrode branch terminal 319D; and a power board 700 having a power board P bus bar and a power board N bus bar sealed with an insulating resin member such that a P terminal 701 and an N terminal 702 are exposed for transmitting DC currents. Thus, it is possible to reduce thermal influences on the resin member, and to improve connection durability.
