Indoor heat exchanger and indoor unit of air-conditioning apparatus

An indoor heat exchanger comprising:

• a plurality of heat transfer tubes including respective flow passages therein through which water flows as a heat medium;
• and
• a header configured to distribute water that flows into the header from an inflow tube connected to a heat source side to the plurality of heat transfer tubes, and cause water that collects from the plurality of heat transfer tubes to flow out to an outflow tube to the heat source side,
• wherein the header includes a first plate-like member and a second plate-like member joined to the first plate-like member, and including an inlet port,
• wherein the first plate-like member includes
• a plurality of start-portion openings that communicate with respective start portions of the plurality of heat transfer tubes, and
• a plurality of end-portion openings that communicate respective end portions of the plurality of heat transfer tubes, and
• wherein the second plate-like member includes
• an inlet port through which water flows from the inflow tube into the second plate-like member,
• a distribution recess that is formed opposite to the plurality of start-portion openings and communicates with the inlet port,
• an outlet port through which water flows out to the outflow tube, and
• a collection recess that is formed opposite to the plurality of end-portion openings and communicates with the outlet port.
