<p>Provided is a heat exchanger enabling effective brazing to be performed in a case where a member that covers an end of a header-collector tube body is joined. An outdoor heat-exchanger (20) is provided with header-collector tubes (22, 23) that are connected to flat multi-hole tubes (21b) joined to a plurality of heat-transfer fins (21a). The header-collector tubes (22, 23) are provided with a header-collector tube body (50) and a baffle (60) serving as a lid member. The baffle (60) is a member for covering one end of the header-collector tube body (50). The header-collector tube body (50) is provided with a brazing material (51) on at least the outer circumferential surface thereof. The outer circumferential surface of the header-collector tube body (50) and the outer circumferential surface of the baffle (60) serving as the lid member have portions that are in contact in at least the longitudinal direction of the header-collector tube body (50) and a direction other than the longitudinal direction.</p>
