A sealed condition inspecting device comprising a support unit for supporting an element to be inspected for a sealed condition, a pair of electrodes in contact with the portion to be inspected of the element to be inspected and supported by the support unit, an electrical variable detecting unit for detecting an electrical variable in the portion to be inspected, and a sealed condition judging means for judging the acceptability of a sealed condition based on the electrical variable. In fact, since the acceptability of a sealed condition is judged based on an electrical variable in the portion to be inspected, whether or not a defective sealed condition has occurred can be determined independently of the subjectivity of the operator, whereby a sealed condition can be inspected for a sealed condition without unpacking them, not only inspection work can be simplified but reliability in the quality of an element to be inspected can be improved.
