摘要： PROBLEM TO BE SOLVED: To provide a liquid state detecting sensor that has a liquid concentration detecting element and can appropriately discharge air bubbles having entered an enclosing region and reduce the influence of the air bubbles on concentration detection or the like. SOLUTION: The sensor 1 includes a concentration sensor element 51, a holder member 55 for holding the tip 511 thereof in a state where the tip 511 is projected from an element holding hole 55H4 of itself, and a protector 58. The protector 58 is provided with a liquid circulation hole 58H1 or the like allowing liquid to circulate inside and outside the enclosing region EH. The holder member 55 has a tip surface 554S that faces the enclosing region EH and is orthogonal to the axis AX, and a tapered outer peripheral surface 554T whose diameter increases toward the base end side. In the circulation holes 58H1-58H4, own base end side ends 58H1K-58H4K are located higher than a hole rim 55H4F of the element holding hole 55H4, and the tip side ends 58H1S-58H4S are located lower than the base end side rim 554K of the outer peripheral surface 554T.
