A liquid circulation mechanism includes a supply flow path making a liquid supply source and a liquid discharging head communicate with each other and a collection flow path making the liquid discharging head and a connection portion of the supply flow path communicate with each other, in which a branch portion, a plurality of flow paths branched at the branch portion, and a merging portion, in which the plurality of flow paths are merged, are provided in at least one of the supply flow path and the collection flow path. Pressure adjustment portions, which are provided in the plurality of flow paths and open the flow paths when a pressure on the liquid discharging head side is equal to a predetermined pressure, have different the predetermined pressures for opening the flow paths in the plurality of flow paths.
