PROBLEM TO BE SOLVED: To provide an electronic equipment with key buttons, in which difference of push-down force does not occur between the key buttons whose top face shape is different. SOLUTION: The electronic equipment with the key buttons includes: a key sheet in which the key buttons are formed; and a circuit board at which switches are installed at positions corresponding to the key buttons on the key sheet. Between the key buttons whose top face shape is different among the key buttons whose indication content has the same kind, the switches of different loads are installed. The electronic equipment with the key buttons is manufactured by: determining a target load value which is a target value of pressure at the time of pushing-down the respective key buttons; using the switch having the target load value as characteristics to measure the pressure required to actually push-down the key buttons; and determining, based on differentiation between the target load value and the measured actually measured value, the load value of the switches used at the respective key buttons.
