1. A device for measuring the amount of water in a subject'"'"'s body comprising:

  • a main body part formed in a linear shape; and

    an insertion part extending in a curved shape from one end of the main body part, the insertion part including;

    a tip side insertion part having a tip surface to which a sensor unit is fixed, wherein the sensor unit is brought into contact with a body surface of a subject to measure data regarding water in a subject'"'"'s body,a base end side insertion part supporting the tip side insertion part through a slide mechanism, wherein the slide mechanism allows the tip side insertion part to slide in a direction substantially perpendicular to the tip surface, anda protective member liquid-tightly covering the slide mechanism between the tip side insertion part and the base end side insertion part, wherein the protective member smoothly connects a first outer peripheral surface of the tip side insertion part, wherein the first outer peripheral surface is a first outer most surface that faces radial outward on an exterior of the tip insertion part, and a second outer peripheral surface of the base end side insertion part to each other, wherein the second outer peripheral surface is a second outer most surface that faces radial outward on an exterior of the base end side insertion part;

    wherein at least a first groove is formed on the first outer peripheral surface of the tip side insertion part in a first region to which the protective member is connected over the whole circumference, at least a second groove is formed on the second outer peripheral surface of the base end side insertion part in a second region to which the protective member is connected over the whole circumference, and projections formed on ends of the protective member are fitted with the first and second grooves when the protective member is connected.
