PURPOSE: A digital piano keyboard is provided to realize the touch of acoustic piano keys by providing leaf springs connected to load elements apart from a predetermined distance, thereby simplifying the fixing structure of the leaf spring and realizing the stable supporting. CONSTITUTION: A digital piano keyboard includes a plurality of coupling elements(33) composing black and white keys and formed with holding protrusions(32) to fix load elements(20) at a side of respective plate woods(28). The load elements have coupling holes in the center to fix the coupling elements received via fixing holes(22) of a side of respective plate springs(21). The plate springs have fixing holes at the other sides to be opened for being detachably attached to indent grooves of key shafts(24) protruded from the plate woods, thereby generating elasticity to surfaces of keys.
