A semiconductor device having electrodes formed along a peripheral part thereof in a staggered arrangement of lines including inside-line electrodes, central-line electrodes and outside-line electrodes. The inside-line electrodes are hexagonal shaped with hypotenuses on the central-line electrodes sides thereof. The central-line electrodes are hexagonal shaped with hypotenuses on the inside-line electrode sides thereof. The maximum width of the outside-line electrode wires immediately between the hypotenuses of adjacent inside-line and central-line electrodes depends on the distance between the centers of the inside-line and central-line electrodes, the minimum lengths of the inside-line and central-line electrodes and the electrode protective film, and the minimum length of the corresponding wire. The position and form of the central line electrodes are thus determinable based on the given relationship and the necessary value of current.
