Power converter

A power converter comprising:

• a power conversion circuit configured to convert an input power into a direct current power or an alternating current power;
• a base member made of resin on which the power conversion circuit is mounted, the base member being composed of an insulating material;
• a cover member, wherein the power conversion circuit is housed between the cover member and the base member;
• a coolant flow path provided within the base member, through which a coolant for cooling the power conversion circuit is circulated;
• and
• a temperature sensor provided on the base member and configured to sense the temperature of the coolant circulating through the coolant flow path, wherein the temperature sensor has an electrically conductive member comprising at least a thermistor;
• and
• a resin wall that surrounds the conductive member and projects from a side of the base member on which the power conversion circuit is mounted, such that a portion of the resin wall is located between the electrically conductive member and the power conversion circuit.
