1. A dispenser, comprising:
a pump chamber is formed by a body including a depression and a lid body covering an opening of the body, wherein a first liquid in the pump chamber is discharged from a nozzle portion by performance of a discharge operation that presses the lid body into an inside of the pump chamber to deform the lid body and a second liquid is caused to flow into the pump chamber by release of the discharge operation;
a suction passage having an open end that opens toward the pump chamber; and
a pressing support portion that is disposed to face away from a top surface of the lid body, wherein
the discharge operation is performed by pinching the top surface of the lid body and the pressing support portion from lateral sides of the body,
wherein the suction passage extends along a direction orthogonal to a discharge operation direction of the lid body,
the lid body is formed of a material that is elastically deformable,
when the lid body is pressed in the discharge operation, the lid body bends into the pump chamber,
wherein a part of the lid body is deformable toward the inside of the pump chamber such that, at an inside of the depression, a part of the lid body overlaps with a part of the open end of the suction passage, after the discharge operation is performed, when the open end of the suction passage is viewed from a front direction.
