Method and apparatus for checking the condition of adhesive application in the form of beads on packages, characterized by the steps of causing each package to pass through a light reception area of an infrared sensor so as to receive infrared energy radiating from the beads on the package, detecting a signal output by the sensor in response to the received energy so as to measure at least one of a peak value corresponding to the rise of the received energy, a peak value corresponding to the fall thereof, and a period of time from the rise to the fall; and comparing an obtained value with a reference value so as to determine the condition of the beads.
