To provide a direction indicating apparatus that does not detect a break occurring in an indicator but can detect a break occurring in a direction indicating lamp incorporating an LED element with reliability. The direction indicating apparatus includes a pulse signal generating part (4), a first switching element (NM1), a direction indicating switch (SW), first and second direction indicating lamp units (2L and 2R), a break detecting part (5), a lighting state detecting part (6, 6a), an indicator part (7, 7a) and an indicator driving part (8, 8a). The break detecting part makes the pulse signal generating part change the period of the pulse signal when a driving current (I) corresponding to the pulse wave of a pulse signal (P) is equal to or lower than a predetermined break detection value. The lighting state detecting part that detects the lighting state of the first direction indicating lamp unit and the second direction indicating lamp unit. The indicator part has one or a plurality of indicators (7L, 7R, 7A). The indicator driving part drives the one indicator (7A) and makes the one indicator light up in response to the lighting state detected by the lighting state detecting part or drives at least any of the plurality of indicators (7L, 7R) and makes the indicator light up in response to the lighting state.
