Abstract
An outdoor unit for an air-conditioning apparatus includes a heat exchanger; a bottom plate; and a separation member configured to separate the bottom plate and the heat exchanger. The bottom plate includes a drainage passage that protrudes downward; and one or more drainage holes each formed to protrude downward from the drainage passage. The drainage passage includes a drainage surface inclined downward toward the one drain hole having a width larger than a width of the heat exchanger. The separation member is formed of a metal electrically less noble than a member forming the heat exchanger, or a resin member. The separation member is provided in the drainage passage and shaped to prevent closing of the drainage passage, in which a height to a surface on which the heat exchanger is placed is larger than a height to an upper surface of the drainage passage.
