To provide a toothbrushing promoter for bringing children into the practice of brushing teeth.

In a step 110, a speech signal that says 'Now start by brushing the front teeth.' is read from memory, and the speech output from a speech generating circuit is issued through a speaker. Then the elapse of a timer period T1 set in a step 115 is made sure. Before the timer period T1 has elapsed, a rhythmical melody for rhythmizing toothbrushing or a speech signal of chant or the like is read from memory in a step 120 and is repeatedly issued from the speaker by the speech generating circuit. In a step 125, a speech that says 'Then brush the back teeth.' is issued, and in a step 140 a speech that says 'To end, brush both the tops and bottoms of the teeth's backs.' is issued.
