1. A filter member detachably mounted in a filter case, the filter case being formed with an inflow port through which water flows in and an outflow port through which the water flows out, the filter member comprising:
a filter portion which has a box shape with one open side;
a plurality of through holes with which the filter portion is provided; and
a rib-shaped portion which is configured to partition through holes, among the plurality of through holes, that are adjacent to each other in a longitudinal direction of the filter portion,
wherein the one open side of the filter portion coincides with an up direction of the filter portion, which is orthogonal to the longitudinal direction of the filter portion,
each of the plurality of through holes extends through the filter portion from an inner peripheral surface of the filter portion to an outer peripheral surface of the filter portion,
one side of a longitudinal direction of the filter member is an upstream side of a flow direction of water flowing on the inner peripheral surface, and another side of the longitudinal direction of the filter member is a downstream side of the flow direction of the water flowing on the inner peripheral surface,
at least one of the through holes includes an inflow portion which is located on the inner peripheral surface and through which the water flows in and an outflow portion through which the water flows out, and
the at least one of the through holes is inclined, such that the outflow portion is located further on the other side of the longitudinal direction of the filter member than is the inflow portion.
