PROBLEM TO BE SOLVED: To provide an ion measurement apparatus capable of detecting the amount of ions with high accuracy.SOLUTION: Since when air containing ions is sucked into an air passageway in a chassis from an air intake of the chassis in order to detect the amount of ion within air by an ion detection electrode arranged inside the air passageway, static electricity easy to generate in a plastic chassis is prevented from occurring by anti-static agents and conductive layer or static electricity generated is discharged outside from a gripping section, or a better conductor than a conductive layer through a human body, the amount of ions can be detected with high accuracy. |
