    • A wiring board includes first and second feeding electrodes (2, 3) provided along both sides of an insulating substrate (1), feeding bus lines (4) extending in a traverse direction and connected to both the feeding electrodes, and conductor wirings (6, 8, 12) having one side terminals forming inner leads having protruding electrodes (9, 11, 13) and the other side terminals connected to the feeding bus lines. The inner leads in each unit region are arranged in two lines extending in the traverse direction. The inner leads of a first group are arranged with a dense wiring pitch, and the inner leads of a second group include a dense pitch region in which a wiring pitch is the same as that of the inner leads of the first group, and a sparse pitch region in which a wiring pitch is longer than that of the inner leads of the first group. The inner leads (6) of the first group and the inner leads (12) in the dense pitch region of the second group are connected to the feeding bus line on one side of each region, and the inner leads (8) in the sparse pitch region of the second group are connected to the feeding bus line on the other side of each unit region. Non-uniformity of heights of the protruding electrodes due to a difference in the wiring pitches of the inner leads can be suppressed easily.
    • 布线板包括沿着绝缘基板(1)的两侧设置的第一和第二馈送电极(2,3),馈送沿横向方向延伸并连接到馈电电极的总线(4)和导体布线(6) ,8,12),其一个端子形成具有突出电极(9,11,13)的内部引线,另一个侧端子连接到馈电总线。 每个单元区域中的内引线布置成沿横向方向延伸的两条线。 第一组的内部引线布置成具有致密的布线间距,并且第二组的内部引线包括密集的间距区域,其中布线间距与第一组的内部引线相同,并且稀疏 其中布线间距比第一组的内引线长的间距区域。 第一组的内部引线(6)和第二组的密集间隔区域中的内部引线(12)在每个区域的一侧连接到馈电总线,并且内部引线(8)在稀疏 第二组的音调区域连接到每个单元区域的另一侧的馈送总线。 可以容易地抑制由于内部引线的布线间距的差异导致的突出电极的高度的不均匀性。
