PROBLEM TO BE SOLVED: To provide a device installed in a wiper blade to display an alarm related to the replacement of the wiper blade. SOLUTION: The alarm device includes a housing formed to connect to the wiper blade rotating reciprocally in the wiper device, a counting unit installed in the housing, and formed so as to cumulatively increase the rotational number of the wiper blade by sensing one reciprocating rotation of the wiper blade, a display unit exposed on the housing to display the alarm operated by the counting unit when the rotational number reaches a predetermined value, and a power unit disposed in the housing to supply electric power to the counting unit and the display unit. Thereby, the alarm device automatically warns a user of the replacement time due to wearing of a wiper strip of the wiper blade according to the rotational number of the wiper blade.
