Electrical component housing

An electrical component housing for housing an electrical component, the electrical component housing comprising:

• a resin base portion allowing the electrical component to be mounted;
• a metal cover portion attached to the base portion and configured to cover the electrical component;
• a metal plate in contact with a bottom surface of the base portion in a manner of covering the bottom surface of the base portion;
• and
• a conductive member provided in a through hole that penetrates the base portion in a thickness direction of the base portion, wherein
• the conductive member electrically connects a ground terminal of the electrical component and the metal plate,
• the base portion includes a coolant channel allowing a coolant for cooling the electrical component to flow,
• the coolant channel passes below a position where the electrical component is mounted, and
• the conductive member is integrally fastened, directly below the electrical component, with the electrical component and a conductor connected to the ground terminal of the electrical component.
