Patent ID: 7129588

Claim:
A portable telephone including: an integrated circuit chip module comprising: a first integrated circuit chip including a first power source pad for a first power voltage and a second power source pad for a second power voltage, the first and second power source pads being adjacent to each other, the first power voltage being higher than the second power voltage, a second integrated circuit chip including a third power source pad for the first power voltage and a fourth power source pad for the second power voltage, the third and fourth power source pads being adjacent to each other, and a wiring board including a first power source wire electrically connected to the first power source pad, a second power source wire electrically connected to the second power source pad, a third power source wire electrically connected to the third power source pad, and a fourth power source wire electrically connected to the fourth power source pad, wherein a distance between the first and second power source wires is shorter than a distance between the first or second power source wires and the third or fourth power source wires, and a distance between the third and fourth power source wires is shorter than a distance between the first or second power source wires and the third or fourth power source wires.
