PROBLEM TO BE SOLVED: To provide an infrared sensor capable of preventing damaging to a leg due an external force that might vibrate a heat insulation part, with high performance. SOLUTION: The infrared sensor comprises a base board 1, a temperature detection part 3 which absorbs infrared rays and detects a temperature change due to the absorption, and a heat insulation part 4 which supports the temperature detection part 3 so that the temperature detection part 3 is arranged spacing from one surface of the base board 1 and heat-insulates the temperature detection part 3 and the base board 1. The heat insulation part 4 has a support part 41 which is arranged spacing from the one surface of the base board 1 and on which the temperature detection part 3 is formed on the opposite side of the base board 1 side, and legs 42, 42 connecting the support part 41 and the base board 1. The leg 42 is formed in a meandering shape in a plane orthogonal to the width direction along the one surface of the base board 1. COPYRIGHT: (C)2008,JPO&INPIT
