We have studied the timing property of a Hybrid Avalanche PhotoDiode, Hamamatsu R7110U-07, and attained a time resolution of
σ
t
∼150
ps
for single photons and ⩽100
ps for a few photons under certain conditions of photocathode voltage and diode reverse bias voltage. Relation between the achievable timing resolution and a multiplication gain is discussed, especially in realizing
σ
t
⩽100
ps
for single photons.
