<P>PROBLEM TO BE SOLVED: To improve a space efficiency of wiring materials so as to downsize an electric power conversion device and improve vibration resistance thereof. <P>SOLUTION: The electric power conversion device comprises: a control circuit board that includes a control circuit that controls driving of the switching operation of a switching element; a connector that includes an external connector terminal, a first internal connector terminal, and a second internal connector terminal; a first flexible print substrate that includes one end connected to the first internal connector terminal and the other end connected to the control circuit board; and a second flexible print substrate having one end connected to the second internal connector terminal and the other end connected to the control circuit board. The first internal connector terminal and the second internal connector terminal are arranged side by side along a direction from the upper part to the lower part of the connector. The first flexible print substrate is laminated on the second flexible print substrate and arranged along the direction from the upper part to the lower part of the connector. <P>COPYRIGHT: (C)2013,JPO&INPIT |
