There are provided a keyboard threshold change apparatus and a keyboard in which thresholds of the ON-sensing positions of the keys can be individually changed and the thresholds can be checked with illumination colors.A keyboard threshold change apparatus includes: a keyboard 1 that includes an illumination LED 17 illuminating key tops of a plurality of keys and a threshold change unit 2 capable of changing, for each key among the keys, a threshold used to determine an occurrence of a press of the key; and a computer 3 that is connected to the keyboard and that includes a mouse 38 used to input the threshold and a display unit 36 outputting the threshold input with the mouse as an image, in which when the threshold for a key among the keys is changed with the mouse, the threshold change unit changes, on the basis of the changed threshold for the key from the computer, a threshold for the key in the keyboard, and the illumination LED changes an illumination color of the key for which the threshold is changed to a color corresponding to the threshold.
