Design philosophy for the ion sources for medical facilities are as follows: (1) sufficient beam intensity, a few hundred eµA; (2) long lifetime with good stability; (3) easy operation and easy maintenance; and (4) compactness.  In order to develop such source for future heavy-ion facilities, a compact ECR source has been designed and constructed.  Features of the source are utilizing permanent magnets for both axial and radial field and tuning the microwave frequency from 8 to 11 GHz.  The beam intensity and stability for C4+ were 280 eA and better than 6% during 20 hours with no adjustment of any source parameters.  These results were acceptable for the medical requirements.
