The present invention relates to a method for mass production of an antimicrobial silver-hydroxyapatite complex nanoparticle, and a silver-hydroxyapatite complex powder obtained thereby. The silver-hydroxyapatite complex powder having a particle size distribution in which 80% or more particles are included in a particle size range can be simply and economically mass-produced while controlling a particle size at a micron-level of several hundred nanometers to several micrometers by an ultrasonic pretreatment and a spray drying. The manufacturing method comprises: a step (1) of manufacturing a calcium hydroxide solution at a concentration of 5 to 10 wt%, adding a silver compound to the solution to a concentration of calcium hydroxide of 1 to 20 wt%, and mixing the solution with a phosphoric acid solution; a step (2) of pretreating the mixture with an ultrasonic wave for 5 to 60 minutes; a step (3) of aging the mixture at 50 to 80°C with stirring at 100 to 1,000 rpm for 1 to 12 hours; a step ...
