Liquid ejection head

A liquid ejection head, comprising:

• an element substrate including an ejection port ejecting a liquid;
• a supply flow path that supplies a liquid to the element substrate;
• a collection flow path that collects a liquid from the element substrate;
• a first pressure adjusting mechanism that communicates with the supply flow path, and adjusts a pressure of a liquid flowing in the supply flow path;
• a second pressure adjusting mechanism that communicates with the collection flow path and adjusts a pressure of a liquid flowing in the collection flow path;
• a filter storage chamber including therein a filter that captures foreign matter included in a liquid;
• a first upstream flow path that communicates with the first pressure adjusting mechanism, and supplies a liquid to the first pressure adjusting mechanism;
• a second upstream flow path that communicates with the second pressure adjusting mechanism and supplies a liquid to the second pressure adjusting mechanism;
• and
• a connection section that causes the first upstream flow path and the second upstream flow path to communicate with each other,
• wherein the connection section is provided at a downstream side from the filter.
