1. A sensor chip to be brought in close proximity to a living body for collecting a body fluid and measuring a chemical substance in the body fluid, the sensor chip comprising:
a body fluid collection unit comprising a body fluid collection port and an opening of the body fluid collection port, the body fluid collection port having a surface comprising a first curved surface and a second curved surface, wherein the first curved surface and the second curved surface are surfaces other than the opening and configured to be brought in close proximity to the living body, wherein the opening of the body fluid collection port is configured by the second curved surface, wherein the curvature of the first curved surface and the curvature of the second curved surface are continuous; and wherein the first curved surface and the second curved surface have the same radius of curvature that is 0.5 mm or greater; and
a sensing unit for performing a chemical measurement on the bodily fluid collected by the body fluid collection unit; and
a fluid channel unit defining a fluid channel fluidly connecting the body fluid collection unit and the sensing unit.
