Claim 4:
5. A gas leak inspection system comprising:
a gas leak inspection device comprising:
a gas sensor disposed outside of a hollow inspection target and facing an outer surface of the hollow inspection target; and
an actuator that produces relative movement between the hollow inspection target and the gas sensor while the gas sensor faces the outer surface of the hollow inspection target,
wherein the gas sensor detects a gas that escapes the hollow inspection target,
wherein the actuator produces relative movement between the hollow inspection target and the gas sensor by rotating the hollow inspection target about an axis of the hollow inspection target, and
wherein the gas sensor comprises a plurality of gas sensors spaced apart in a circumferential direction of the hollow inspection target and centered about the axis of the hollow inspection target; and

an additional gas leak inspection device including an additional gas sensor and that covers a partial area of the outer surface of the hollow inspection target and inspects the partial area for presence of a gas leak.
