Liquid discharge head and liquid discharge apparatus

A liquid discharge apparatus comprising:

• a liquid discharge head including:
• a discharge element substrate configured to discharge a liquid;
• an upstream-side flow path connected to the discharge element substrate and configured to supply a liquid to the discharge element substrate;
• a downstream-side flow path connected to the discharge element substrate and configured to collect a liquid from the discharge element substrate;
• and
• a pump connected to each of the upstream-side flow path and the downstream-side flow path and configured to cause a liquid within the downstream-side flow path to flow out to the upstream-side flow path, the pump including a pump outflow hole for causing the liquid within the downstream-side flow path to flow out to the upstream-side flow path, an opening of the pump outflow hole facing upward in a substantially vertical direction in a use state of the liquid discharge head;
• and
• a carriage on which the liquid discharge head is mounted, the carriage being configured to perform scanning on an object onto which a liquid is to be discharged from the liquid discharge head.
