Zusammenfassung:	To propose an indoor machine capable of suppressing occurrence of electric corrosion in a refrigerant pipe, and an air conditioner comprising the indoor machine.SOLUTION: An indoor machine (1) comprises a casing (21), a heat exchanger (15) housed in the casing (21), and a connection pipe (31) connected to the heat exchanger (15) through which a refrigerant flows. The connection pipe (31) comprises a first refrigerant pipe (311) having one end connected to the heat exchanger (15) and made of a first metal, and a second refrigerant pipe (312) made of a second metal that is nobler in potential than the first metal of the first refrigerant pipe (311). One end of the second refrigerant pipe (312) is connected to the other end of the first refrigerant pipe (311) inside the casing (21).SELECTED DRAWING: Figure 7 【課題】冷媒配管における電蝕の発生を抑制できる室内機およびその室内機を備えた空気調和機を提案する。【解決手段】室内機(１)は、ケーシング(２１)と、ケーシング(２１)に収容された熱交換器(１５)と、熱交換器(１５)に接続され、冷媒が流れる接続配管(３１)とを備える。接続配管(３１)は、一端が熱交換器(１５)に接続されると共に、第１の金属で形成された第１冷媒配管(３１１)と、第１冷媒配管(３１１)の上記第１の金属に対して電位的に貴な第２の金属で形成された第２冷媒配管(３１２)とを備える。第２冷媒配管(３１２)の一端は、第１冷媒配管(３１１)の他端にケーシング(２１)内で接続されている。【選択図】図７
