    摘要: In an electronic-component mounting structure, an electronic component (2) has a surface. First electrodes (1) provided on the surface of the electronic component (2) are arranged in a first array. Second electrodes (3) provided on a base board (4) are arranged in a second array corresponding to the first array. The second electrodes (3) correspond to the first electrodes (1) respectively. Solder bumps (9) connect the first electrodes (1) and the second electrodes (3) respectively. The first electrodes (1) include first outermost electrodes (1b) located in an outer area of the first array. The second electrodes (3) include second outermost electrodes (3b, 3c) located in an outer area of the second array. The second outermost electrodes (3b, 3c) correspond to the first outermost electrodes (1b) respectively. An outer edge (X1, Z1) of each of the second outermost electrodes (3b, 3c) extends outward of an outer edge (Y1) of a corresponding first outermost electrode (1b) with respect to the first and second arrays. A distance between an outer edge (X1, Z1) of each of the second outermost electrodes (3b, 3c) and an outer edge (Y1) of a corresponding first outermost electrode (1b) is greater than a distance between an inner edge (X2, Z2) of the second outermost electrode (3b, 3c) and an inner edge (Y2) of the corresponding first outermost electrode (1b) with respect to the first and second arrays.
