PROBLEM TO BE SOLVED: To provide an opening/short circuit inspection method and an opening/short circuit inspection device which detect a short circuit, without depending on visual observation or a probe. SOLUTION: An integrated circuit 10 includes a power source terminal P11 to which the power source is supplied from the outside, a circuit 101 which operates based on the power source, and the external terminals P10 consisting of N individual ( N is 3 or more natural numbers ) in which a first potential H and a second potential L which is different from the first potential H output arbitrarily by control from outside, which are connected into a first circuit 101, juxtaposed together with predetermined direction. In the external terminals P10, the first potential is made output into external terminals from one side of direction into M individual ( M is 1 to N natural numbers ), the second potential which is different from the first potential is made output into external terminals from (M+1) individual to N individual, when the current value flowing through a power source terminal 11 becomes over a predetermined value, it is determined that the external terminal between M individual and (M+1) individual is short circuited.
