PROBLEM TO BE SOLVED: To provide an alarm device capable of outputting an alarm based on detection of a picking action by a picking action detection sensor, and pushing operation to a pushbutton switch, with excellent operability of the pushbutton switch. SOLUTION: This device is installed close to a lock on a door. As the picking action sensor 4 detects vibration (sound) by a picking action, it sends a detection signal to an alarm control means, so that the alarm is outputted to the external through a speaker 3 in it. In addition, in case of invasion of a thief other than through the door 31 by a picking action, that is through a window, for example, the alarm can be outputted by pushing the pushbutton switch 9.
