摘要： An alarm device including a sensor having sufficiently high detection sensitivity is provided. The sensor 51 in the alarm device 41 is disposed such that a plan M perpendicular to the detection direction P of the sensor 51 is aligned at a specified angle null with respect to a plane V perpendicular to the sun visor 72 (the lower surface 61a), where the specified angle null should be set to be an approximately mean value of the expected minimum angle nullnull0null and the expected maximum angle nullnull40null (in this case, nullnull20null). In other words, the plane M perpendicular to the detection direction P of the sensor 51 should be aligned at an angle null (nullnull90null nullnull) of less than 90null with respect to the sun visor 72 (the lower surface 61a). The present invention is applicable to such an alarm device mounted onto a vehicle for preventing the vehicle theft.
