An ion sensor includes a sensor main body (6) having a channel (6d) for a sample and an opening (6e, 6f) connected to the channel (6d), a responsive portion (71, 81) which is filled in the opening (6e, 6f) and selectively responds to a specific ion, an electrode (72, 82) which has a ring shape, is set such that a central axis of the ring is substantially perpendicular to a central axis of the channel (6d), and senses the response, and an output terminal (73, 83) which is formed out of one metal plate out of which the electrode (72, 82) is formed, has a pin shape, and is held by the sensor main body (6) such that an axis extends along a direction substantially perpendicular to the central axis of the channel (6d) and the central axis of the ring. |
