Outdoor unit for refrigeration cycle apparatus

An outdoor unit for a refrigeration cycle apparatus, comprising:

• a casing that is an outer shell;
• an air-sending device housed in the casing and configured to generate an airflow;
• and
• an electric component box housed in the casing, disposed above the air-sending device, and including a bottom plate on which control components are placed,
• the bottom plate of the electric component box including
• an inclined portion on which a first component among the control components is fixed, the inclined portion being inclined such that an upstream end of the inclined portion on an upstream side of the airflow is positioned above a downstream end of the inclined portion on a downstream side of the airflow, and
• a horizontal portion on which a second component among the control components is fixed, the horizontal portion horizontally extending to the downstream side of the airflow and having an upstream end on the upstream side of the airflow that is connected to the downstream end of the inclined portion on the downstream side of the airflow.
