Abstract
A metal detectorincludes a detection signal acquisition unit, a threshold value setting and updating unit, and a determination unit. The detection signal acquisition unitacquires a detection signal that changes according to the detection strength for a rebar Wcontained in concrete W, on the surface of the concrete W. The threshold value setting and updating unitsets a threshold value in order to determine the presence or absence of the rebar Won the basis of the maximum value and/or the minimum value included in the acquisition results for the detection signal acquired by the detection signal acquisition unit. The determination unitdetermines the presence or absence of the rebar Wby using the threshold value set in the threshold value setting and updating unit
