A fluid machine, comprising: an impeller mounted to a rotation shaft; a housing which houses the impeller rotatably; and an intake pipe for supplying a fluid to the housing, wherein the intake pipe includes at least: a first bend portion disposed on a first plane; a second bend portion disposed at a downstream side of the first bend portion and on a second plane which is different from the first plane, the second bend portion including an upstream section having a center axis oriented along a center axis of a downstream section of the first bend portion and a downstream section having a center axis oriented along an axial direction of the impeller at a front of the impeller, a straight pipe portion having an upstream end connected to a downstream end of the second bend portion and a downstream end connected to the housing, wherein the intake pipe has a constant cross-sectional shape from an upstream end of the first bend portion to the downstream end of the straight pipe portion, characterised in that an intersection angle between the first plane and the second plane is in a range of not less than 45° and not more than 135°, and wherein a distance between: an intersection (β) between the center axes of the upstream section and the downstream section of the second bend portion; and a front end of vanes of the impeller is not more than five times a pipe diameter of the intake pipe. an impeller mounted to a rotation shaft; a housing which houses the impeller rotatably; and an intake pipe for supplying a fluid to the housing, wherein the intake pipe includes at least: a first bend portion disposed on a first plane; a second bend portion disposed at a downstream side of the first bend portion and on a second plane which is different from the first plane, the second bend portion including an upstream section having a center axis oriented along a center axis of a downstream section of the first bend portion and a downstream section having a center axis oriented along an axial direction of the impeller at a front of the impeller, a straight pipe portion having an upstream end connected to a downstream end of the second bend portion and a downstream end connected to the housing, a first bend portion disposed on a first plane; a second bend portion disposed at a downstream side of the first bend portion and on a second plane which is different from the first plane, the second bend portion including an upstream section having a center axis oriented along a center axis of a downstream section of the first bend portion and a downstream section having a center axis oriented along an axial direction of the impeller at a front of the impeller, a straight pipe portion having an upstream end connected to a downstream end of the second bend portion and a downstream end connected to the housing, wherein the intake pipe has a constant cross-sectional shape from an upstream end of the first bend portion to the downstream end of the straight pipe portion, characterised in that an intersection angle between the first plane and the second plane is in a range of not less than 45° and not more than 135°, and wherein a distance between: an intersection (β) between the center axes of the upstream section and the downstream section of the second bend portion; and a front end of vanes of the impeller is not more than five times a pipe diameter of the intake pipe.
