Liquid ejection head and method of manufacturing same

A liquid ejection head comprising:

• an ejection port member that includes an ejection port that ejects a liquid;
• an energy generating element that generates energy for ejecting the liquid from the ejection port;
• a terminal electrically connected to the energy generating element;
• and
• a substrate portion that supports the ejection port member, the energy generating element, and the terminal,
• wherein the terminal is connected to a wire member that supplies electric power that drives the energy generating element to the energy generating element,
• wherein the substrate portion includes a hole portion formed from a surface of the substrate portion on a side opposite to a surface of the substrate portion on which the terminal is provided to a surface where the terminal is exposed, and
• wherein an area of the surface of the substrate where the terminal is exposed is smaller than an area of an opening of the hole portion,
• wherein the wire member is a wire for wire lead bonding or a flying lead wire, and
• wherein the wire member is not directly in contact with a side wall surface of the hole portion.
