Abstract (en)
An air conditioner includes an indoor unit (1) and an electrical unit (8) placed on a side of a front wall (1b) of the indoor unit (1). The electrical unit (8) accommodates a substrate (8c) therein, on which an alternating-current circuit block (132), a high-voltage direct-current circuit block (133) and a low-voltage direct-current circuit block (134) are arrayed in order from a side of an alternating-current power cord connected to an alternating-current power source (131). The alternating-current circuit block (132) includes a noise filter (139) to restrain unnecessary radiation noise from leaking to a primary side. A ground pattern (140) of the low-voltage direct-current circuit block (134) and a pattern (141) of the alternating-current circuit block (132) positioned on the primary side of the noise filter (139) are placed adjacent to each other to form a stray capacitance (143) between those patterns (140, 141). The ground pattern (140) of the low-voltage direct-current circuit block (134) is connected at an end portion thereof to the earth.
