PROBLEM TO BE SOLVED: To provide a level adjustment device that can adjust a sound volume level of a detailed audio signal output requested by a user in a short time. SOLUTION: A rough adjustment level or a fine-adjustment level is read from a storage section 4 that stores a rough adjustment table where rough adjustment levels are stored and a fine adjustment table where fine-adjustment levels are stored in response to a rough adjustment operation input signal outputted from a rough adjustment operation input signal generating section 2A that generates the rough adjustment operation input signal, and a fine- adjustment operation input signal outputted from a fine adjustment operation input signal generating section 2B that generates the fine-adjustment operation input signal, an arithmetic section 3 calculates the read rough adjustment level or fine adjustment level to generate a calculated adjustment level, and a level adjustment section 5 adjusts sound volume level of an audio signal output on the basis of the generated arithmetic adjustment level.
