1. A heat exchanger that heats or cools water with a fluid, the heat exchanger comprising:
a heat transfer portion that comprises:
fluid flow paths through which a fluid flows; and
water flow paths through which water flows and that are adjacent to the fluid flow paths;
an upstream portion that forms an upstream space on an upstream side of the water flow paths; and
a distributor plate disposed in the upstream space between the water flow paths and a water entering port and that distributes water that flows into the upstream space from the water entering port to the water flow paths, wherein
the distributor plate comprises:
an opposing portion that opposes the water entering port; and
a non-opposing portion that does not oppose the water entering port,
both of the opposing portion and the non-opposing portion are disposed in the upstream space,
the distributor plate has:
a first through hole in the opposing portion; and
a second through hole in the non-opposing portion, and
the first through hole is smaller than the second through hole.
