摘要： A refrigerant flow path unit (10) includes: a unit body (11) including a plurality of plates (21, 22, 23) that are laminated together, and having an interior in which a refrigerant flow path (15) is formed; a refrigerant pipe (12, 13, 103); and a first brazing filler metal (B3, B4) that joins the unit body (11) to the refrigerant pipe (12, 13, 103). The unit body (11) includes a first plate (21) formed with a first opening (21a) and a second plate (22) formed with a second opening (22a) that communicates with the first opening (21a), the second plate (22) being laminated to the first plate (21). The refrigerant pipe (12, 13, 103) is inserted into the first opening (21a) and the second opening (22a). The first brazing filler metal (B3, B4) joins the inner peripheral surface of the first opening (21a) and the inner peripheral surface of the second opening (22a) to the outer peripheral surface of the refrigerant pipe (12, 13, 103).
