A vehicle seat includes sheet-shaped sensors attached to a seat back, and can measure the heart rate of a seated passenger based on vital signals of the seated passenger detected by the sheet-shaped sensors. At each sheet-shaped sensor, a sensor overlap reduction section is provided to reduce partial overlapping of the sheet-shaped sensor when the seated passenger leans on the seat back. Specifically, each sheet-shaped sensor includes a first cutout extending toward the center of the sheet-shaped sensor at an outer peripheral portion of the sheet-shaped sensor, and a second cutout formed continuously from the first cutout and extending opposite to the center along the outer peripheral portion of the sheet-shaped sensor. ## Claims ### Claim 1 A vital information measurement device comprising: a sheet-shaped sensor is attached to a cushion pad and is configured to detect a vital signal of a subject that is a human or an animal, and a skin that covers the cushion pad, wherein: the vital information measurement device is configured to measure vital information of the subject based on the vital signal detected by the sheet-shaped sensor, a distribution cable is electrically connected to the sheet-shaped sensor and is configured to transmit the vital signal detected by the sheet-shaped sensor, a skin insertion groove, into which an end of the skin is inserted, is formed in the cushion pad, and the distribution cable extends across the skin insertion groove. ### Claim 2 (depends on 1) The vital information measurement device according to claim 1, wherein: a cable housing recess is formed in a front portion of the cushion pad that is opposite to the distribution cable. ### Claim 3 (depends on 2) The vital information measurement device according to claim 2, wherein: the cable housing recess and the skin insertion groove are connected together. ### Claim 4 (depends on 1) The vital information measurement device according to claim 1, wherein: the distribution cable is arranged at a side portion of the cushion pad in a seat width direction. ### Claim 5 (depends on 4) The vital information measurement device according to claim 4, wherein: the sheet-shaped sensor comprises a first sensor and a second sensor;
