Control board for on-vehicle electric compressor, on-vehicle electric compressor provided with same, and method for manufacturing control board for on-vehicle electric compressor

Abstract

[Problem] To provide a control board for an on-vehicle electric compressor, which can suppress or prevent an increase in electromagnetic noise when a capacitor element is not connected between power supply wiring and ground wiring. [Solution] This control board for an on-vehicle electric compressor comprises: a separation pattern (43) that has a power supply pad (46), a grounding pad (47), and a GND pad (48), and is separated from power supply wiring (27), GND wiring (28), and ground wiring (37); a power supply-side pad (51) provided to the power supply wiring (27); a ground-side pad (52) provided to the ground wiring (37); and a GND-side pad (53) provided to the GND wiring (28). The power supply pad (46) can be connected to the power supply-side pad (51) via solder (61), the GND pad (48) can be connected to the GND-side pad (53) via solder (61), and the grounding pad (47) can be connected to the ground-side pad (52) via a capacitor element (38A).
