The invention provides an inspection device for a thin film battery, which can detect a poor sealing part of a heat sealing part. According to the present invention, it is possible to provide an inspection device (200) for a thin-film battery (100) provided with an electrode body and a film exterior body in which the electrode body is housed and which has a heat-sealing part on the periphery. The inspection device (200) is provided with: a temperature measurement device (210) for measuring the temperature distribution of the heat-seal part; and a first determination unit (241) that controls the temperature measurement device for a predetermined period of time after the heat-seal part is formed in the film exterior body, and determines the presence or absence of a poor-seal site on the basis of the measured temperature distribution. 本发明提供能够检测热封部的密封不良部位的薄膜电池的检查装置。根据本发明，可提供一种具备电极体和在内部收纳上述电极体并在周缘具有热封部的膜外装体的薄膜电池(100)的检查装置(200)。上述检查装置(200)具备：温度测量装置(210)，测量上述热封部的温度分布；和第1判定部(241)，当在上述膜外装体形成了上述热封部之后，在规定的时间内控制上述温度测量装置，
