Connection terminal structure, method for manufacturing connection terminal structure, and connection terminal structure substrate

A connection terminal structure comprising:

• a support member including a first surface and an opening part formed in the first surface;
• and
• at least one connection terminal formed on the first surface, the connection terminal including
• a fixing part,
• a connection part configured to connect to a connection object, and
• a spring part communicating between the fixing part and the connection part;
• wherein a portion of the fixing part is exposed in the opening part,
• wherein the support member, the spring part, and the connection part are bent diagonally upward with respect to the exposed portion of the fixing part and project toward the connection object,
• wherein a direction in which the support member, the spring part, and the connection part project is toward the first surface of the support member,
• wherein the support member, the spring part, and the connection part form an obtuse angle with respect to the fixing part,
• wherein the support member includes a second surface on a side opposite to the first surface,
• wherein the opening part penetrates the support member from the first surface of the support member to the second surface of the support member,
• wherein the opening part is formed directly below the fixing part of the connection terminal.
