<p>PROBLEM TO BE SOLVED: To provide a terminal part wherein a terminal forming area is narrowed without lowering reliability of connection, in a high density substrate having many terminals required for connection to outside circuits. SOLUTION: A terminal 2 takes the form of a trapezoid, and the terminal part 1 is formed by alternately disposing the long sides and the short sides of the trapezoids on the connecting side for a leader line 4. At this time, the widely formed parts of the terminals 2 are provided so as to form a zigzag shape, and the wide parts provided in the zigzag shape are used for connection to outside circuits as contact areas 3.</p> |
