1. An electrical junction box comprising:
a heat generating component;
a cooling unit being configured to cool the heat generating component; and
a resin case being configured to hold the heat generating component and the cooling unit, wherein
the cooling unit includes
a metal plate being formed in a shape conforming to a shape of the heat generating component,
a metal pipe through which a coolant flows, the metal pipe being disposed along and in contact with the metal plate, and
a heat transfer member having insulating properties and intervening between the heat generating component and the metal plate.
