1. A method of manufacturing a sensor that includes a cylindrical casing in which an opening portion is formed at one end and a detection part including a core having a coil is accommodated in another end and in which an electronic component is accommodated, a cylindrical clamp in which a recessed part having a sealing ring attached thereto is formed in an outer periphery and one end thereof is inserted into the opening portion, and the sealing ring which is attached to the recessed part and is disposed between the casing and the clamp, the method comprising:
a step of forming a first component of the clamp using a first divided mold, the first component including a cylindrical main body portion and a first part which is located on one end side of the main body portion and constitutes a portion of the recessed part,
wherein the first divided mold has a dividing surface intersecting the main body portion and is divided to be able to separate in an axial direction of the main body portion; and
a step of forming a second component of the clamp constituting another portion of the recessed part using a second divided mold so that the second component is formed integrally with the first component, and providing the recessed part,
wherein the second component is inserted into the opening portion.
