Method of measuring adhesive strength
23 Nov 20
A method of measuring adhesive strength between an element body and a porous protection layer that are included in a sensor element includes (a) a step of holding a portion of the element body where the porous protection layer is absent with an elastic force exerted by a holding jig, and placing a peeling jig at a position between the porous protection layer and the holding jig in the longitudinal direction such that the element body is allowed to move in the longitudinal direction while the porous protection layer is prevented from moving in the longitudinal direction toward the holding jig; and (b) a step of moving, after the step (a), the peeling jig pushes the porous protection layer in the longitudinal direction, and measuring the adhesive strength of the porous protection layer.
