    摘要: PROBLEM TO BE SOLVED: To provide an IC chip capable of preventing electric short-circuiting between wiring lines while securing the relaxation of stress accompanied by the cutting of a semiconductor wafer when electric connection between a pad of the IC chip and an outer side is wired by using a conductive ink.
    SOLUTION: The IC chip has a groove 12 formed along an inner periphery on the IC chip 11, and the pad 14 which is arranged more inside of the groove 12, and electrically connected to the outer side by ink jet wiring lines 15 using ink containing a conductive material. Short-circuit preventive parts 16 are arranged for preventing the ink jet wiring lines from being short-circuited when the ink-jet wiring lines 15 are wired in the vicinity of an intersection where the ink jet wiring lines 15 intersect the groove 12.
