1. A heat exchanger, comprising
a plurality of heat exchange members arranged in a first direction so as to be spaced apart from each other,
wherein each of the plurality of heat exchange members includes:
a heat transfer pipe extending in a second direction intersecting with the first direction; and
a heat transfer plate provided to the heat transfer pipe along the second direction,
wherein the heat transfer plate includes an extending portion extending away from the heat transfer pipe in a third direction intersecting with each of the first direction and the second direction,
wherein the heat transfer plate is a member formed separately from the heat transfer pipe,
wherein the heat transfer pipe is a flat pipe,
wherein a thickness direction of the flat pipe matches with the first direction,
wherein an outer peripheral surface of the flat pipe includes a first thickness-direction end surface and a second thickness-direction end surface, which are opposed to each other in the thickness direction of the flat pipe,
wherein the heat transfer plate has a heat transfer plate main body portion overlapping the first thickness-direction end surface,
wherein the heat transfer plate main body portion has a curved portion configured to cover the outer peripheral surface of the flat pipe,
wherein the outer peripheral surface of the flat pipe includes an upstream-side end surface, and a downstream-side end surface,
wherein the upstream-side end surface and the downstream-side end surface are opposed to each other in the width direction of the flat pipe,
wherein the curved portion covers the upstream-side end surface,
wherein the second thickness-direction end surface and the downstream-side end surface are uncovered and exposed to air,
wherein the extending portion includes a first extending portion which extends from an end of the curved portion, and
wherein the first extending portion is arranged in alignment with a position of the second thickness-direction end surface in the thickness direction of the flat pipe.
