PROBLEM TO BE SOLVED: To provide a biometric information collection sensor capable of collecting biometric information even in a narrow space or at a distant position, and biometric information collection using the biometric information collection sensor. SOLUTION: A light emitting unit 2, a light receiving unit 3 and 4, and a housing unit 10 that houses the light emitting unit 2 and the light receiving unit 3 and 4 and extends in one direction are provided at least, and the housing unit 10 is provided. The light emitting unit 2 and the light receiving units 3 and 4 are arranged side by side, and the mounting surface portion 14 facing the measurement target side when collecting biological information and the tip portion 31 of the rod-shaped member 30 holding the housing portion 10 can be pulled out. A biometric information collection sensor 1 provided with groove portions 24a and 24b to be inserted into the body, and an adapter portion 20 extending in one direction.
