Abstract: An electric equipment assembly has a frame with various electric components attached to the frame. The electric components include a control circuit board mounted with operating control elements and an inverter control element. Preferably the electric equipment assembly is disposed in outdoor units of an air conditioner. Each outdoor unit includes a structure in which the inside of a casing has a generally rectangular parallelepiped box shape divided into a fan chamber and a machine chamber by a partition plate extending vertically. The frame is provided such that a substrate surface of the control circuit board is positioned along a partition plate and is also inclined to a front side of the unit casing, with the frame provided in a unit casing so that an increase in airflow resistance in a fan chamber is prevented and the on-site workability is ensured at the same time.
