There is provided a flow channel member which is configured by laminating a plurality of side wall units and inside which a flow channel is provided, wherein occurrence of joint failure of the side wall units are reduced. A flow channel member includes a cover unit, a side wall unit, and a bottom plate unit, wherein a flow channel through which a fluid flows is provided inside the flow channel member, and a gap which communicates with the flow channel is provided between the cover unit and the side wall unit. According to the flow channel member, since the gap which communicates with the flow channel is located between the cover unit and the side wall unit, a contact area between the flow channel and the fluid increases, and thus heat exchange efficiency with the cover unit may be increased. |
