Abstract

An ion sensor includes a sensor main body having a channel for a sample and an opening connected to the channel, a responsive portion which is filled in the opening and selectively responds to a specific ion, an electrode 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, and senses the response, and an output terminal which is formed out of one metal plate out of which the electrode is formed, has a pin shape, and is held by the sensor main body such that an axis extends along a direction substantially perpendicular to the central axis of the channel and the central axis of the ring.

Claims (4)

1 . An ion sensor manufacturing method comprising:

inserting a pin into a channel for a sample formed in a sensor main body;

coating the inserted pin and a wall surface of an opening connected to the channel with a solution prepared by dissolving, in a solvent, a responsive material which selectively responds to a specific ion, such that the opening is filled with the solution; and

removing the pin from the channel after the solvent in the coated solution has evaporated.
