摘要： PROBLEM TO BE SOLVED: To provide a spray pressure measuring apparatus for precisely measuring a jet state of spray without being damaged.SOLUTION: A second spring member 270 to be a plate spring of smaller spring constant than a first spring member 260 is provided in the center in the longitudinal direction of the first spring member 260 to be a plate spring for holding an optical fiber 250 in the state that it elastically deforms as a pressure transmission part 222 is displaced. Even in the environment where pressure is very weak and electromagnetic wave noise occurs, the weak pressure can be measured precisely. Even in situations where excessive pressure is given and the pressure transmission part 222 is considerably displaced, the second spring member 270 is elastically deformed and the first spring member 260 for holding the optical fiber 250 has a relatively small elastic deformation amount. It is prevented that a large ultimate tensile strength radically operates on the optical fiber 250 and that the optical fiber 250 is damaged by the breaking or the like.
