Bioinformation measurement device

A device, comprising:

• a seat;
• a bioinformation measurement device for measuring a bioinformation of a seated person who is seated on the seat,
• wherein the bioinformation measurement device comprises:
• a sensor which outputs an electric signal according to the bioinformation, and comprises a leading wire including a transmission path for the electric signal;
• a circuit substrate comprising an input terminal connected to the leading wire of the sensor and configured to receive the electric signal from the sensor, and an amplification unit configured to amplify the electric signal input to the input terminal;
• and
• a guard ring disposed in a manner surrounding the sensor,
• the sensor and the circuit substrate are disposed in positions adjacent to each other in the seat,
• a terminal portion of the leading wire extends from a portion of the sensor adjacent to the circuit substrate and is connected to the input terminal in a state abutting the input terminal, and
• the sensor, the guard ring, and the circuit substrate are disposed in a state arranged along a width direction of the seat.
