A non-contact frequency automatic tuning filter with an antileakage chamber includes a first casing with a first cavity formed at a first opening of the first casing, a moving part, and a second cavity. The second cavity has a second casing, a chamber formed in the second casing, and second and third openings penetrating through the second casing. The moving part is plugged from the third opening into the first cavity or from the third opening into a space between the third opening and the first cavity. The second opening proximate to the moving part constitutes a part of the chamber. The second casing has a spacing portion proximate to the moving part for separating the moving part and chamber. The first and second casings are not in contact with the moving part. The invention can prevent leakage of electromagnetic waves and unstable frequency shifting.
