A terminal (300) is attached to a sensor sheet (100) using a tongue piece (131) that extends from the sensor sheet (100). This makes it possible to reduce a sense of discomfort in a subject caused by the presence of the terminal (300), and to realize a biological-information measurement device with which it is possible to mitigate a sense of discomfort in a subject caused by the device, to a greater extent than in a case in which, e.g., the entire reverse surface of the terminal (300) is secured to the sensor sheet (100).
