1. An outdoor unit for an air-conditioning apparatus, the outdoor unit comprising:
a machine chamber;
a compressor provided in and at a bottom of the machine chamber;
a reactor provided in the machine chamber and higher than the compressor and configured to rectify an electric current to be supplied to the compressor;
a peripheral soundproof material that extends as high as a position of the reactor and encloses the compressor; and
an upper soundproof material that covers the compressor and is placed on the peripheral soundproof material,
a connecting terminal projecting from and disposed on an upper surface of the reactor, to a wire extracted from an electrical substrate connecting to the connecting terminal,
the upper soundproof material having a cut outlined around the connecting terminal,
the upper soundproof material covering at least part of the upper surface of the reactor, and the peripheral soundproof material and the upper soundproof material each being one of a sheet, a board, urethane, sponge, fabric, and glass wool that reduces or blocks an operating sound emitted from the compressor or an electromagnetic sound emitted from the reactor,
wherein the peripheral soundproof material has upper end portions that are at a uniform height and an other upper end portion that is at a height different from the uniform height, the other upper end portion being a portion where the reactor is present, and
wherein the upper soundproof material is placed on the upper end portions of the peripheral soundproof material that are at the uniform height, and is not placed on the other upper end portion of the peripheral soundproof material that is at a height different from the uniform height and where the reactor is present.
