PROBLEM TO BE SOLVED: To provide a biosignal detector capable of reducing the cost without narrowing a detection range. SOLUTION: This detector disposed between a bedstead frame A and a mattress B mounted on the bedstead frame A is provided with a base part 2 to be mounted on the bedstead frame A, three sensor elements 1A-1C mounted on the base part 2 and converting a pressure attributed to a person lying on the mattress B into an electric signal, a connecting conductor 5 for electrically connecting output terminals of the respective sensor elements 1A-1C together, a pressure transmission part 3 disposed integrally covering the whole of the respective sensor elements 1A-1C and the connecting conductor 5 and transmitting the pressure attributed to the person lying on the mattress B, and a cover part 4 covering the pressure transmission part 3 and having a circumferential edge fixed to the base part 2, wherein the sensor elements 1A-1C are aligned with a prescribed interval apart.
