Semiconductor module

A semiconductor module comprising:

• a plurality of semiconductor units arrayed in a line;
• a first sensing terminal disposed on a first side of the line of the plurality of semiconductor units;
• and
• a second sensing terminal disposed on a second side of the line of the plurality of semiconductor units, wherein:
• each of the semiconductor units includes:
• an upper arm circuit including a first semiconductor chip;
• a lower arm circuit including a second semiconductor chip;
• and
• an insulating substrate including a first conductor pattern through which a principal current output from the first semiconductor chip and a principal current to be input to the second semiconductor chip flow,
• the first sensing terminal is electrically connected to an emitter of a first semiconductor chip included in any one of the plurality of semiconductor units via a first wiring route including a first sensing conductor pattern provided on the insulating substrate, and
• the second sensing terminal is electrically connected to the emitter of the first semiconductor chip that is connected to the first sensing terminal, via a second wiring route including a second sensing conductor pattern provided on the insulating substrate separately from the first conductor pattern, without passing via the first conductor pattern.
