| 1. A method of manufacturing a porous-bio-implant having a connecting member formed integrally therewith, comprising the steps
of:
inserting a connecting member into an upper opening of a pyrex tube;
inserting a metal powder into the pyrex tube through a lower opening of the pyrex tube;
inserting an upper electrode through the upper opening of the pyrex tube and resting the upper electrode on an upper surface
of the connecting member, and inserting a lower electrode through the lower opening of the pyrex tube;
supplying a low voltage from a power supply that is connected to the upper and lower electrodes;
boosting the low voltage to a high voltage by subjecting the low voltage to a voltage booster;
charging the high voltage boosted by the voltage booster in a condenser through a first switch; and
discharging the high voltage charged in the condenser instantaneously through a vacuum switch to sinter the metal powder in
the pyrex tube, thereby forming a bio-implant, having a porous outer layer and a inner solid tissue, integrally with the connecting
member.
