To provide a work machine and a position detection device which can accurately detect a connection position between a second action part and a third action part with simple structures.SOLUTION: A work machine includes a work machine body, a first action part (boom), a second action part (arm), an imaging part, and a position detection part. The first action part has one end connected to the work machine body, and is displaced with respect to the work machine body. The second action part is linked with the other end of the first action part. The imaging part is provided on the work machine body, and images the one end on the link side, in the second action part. The position detection part detects a position of the other end on a side where a third action part (bucket) is linked, in the second action part, on the basis of the image of the imaging part.SELECTED DRAWING: Figure 5 【課題】簡単な構成で、第２作用部と第３作用部の連結位置を精度よく検出することができる作業機械、および位置検出装置を提供する。【解決手段】作業機械は、作業機本体と、第１作用部（ブーム）と、第２作用部（アーム）と、撮像部と、位置検出部とを備える。第１作用部は、作業機械本体に一端が接続し、前記作業機械本体に対して変位する。第２作用部は、前記第１作用部の他端にリンクする。撮像部は、前記作業機械本体に設けられ、前記第２作用部のうち、前記リンク側の一端を撮像する。位置検出部は、前記撮像部の画像に基づいて、前記第２作用部のうち、第３作用部（バケット）がリンクする側の他端の位置を検出する。【選択図】図５
