The Jupiter family comet 169P/NEAT (previously known as asteroid 2002 EX12) has a dynamical association with the -Capriconid meteoroid stream. In this paper, we present photometric observations of comet 169P/NEAT to further investigate the physical characters of its disintegration state related to the stream. The comet shows a point-like surface brightness profile limiting contamination due to coma emission at 4% at most, indicating no evidence of outgassing. An upper limit on the fraction of the surface that could be sublimating water ice of <10-4 is obtained with an upper limit to the mass loss of 10-2 kg s-1. The effective radius of nucleus is found to be 2.3±0.4 km. Red filter photometry yields a rotational period of 8.4096±0.0012 hr, and the range of the amplitude 0.29±0.02 mag is indicative of a moderately spherical shape having a projected axis ratio 1.3. The comet shows a redder colors than the Sun, being compatible with other dead comets candidates. The calculated lost mass per revolution is 109 kg. If it has sustained this mass loss over the estimated 5000 yr age of the -Capriconid meteoroid stream, the total mass loss from 169P/NEAT ( 1013 kg) is consistent with the reported stream mass ( 1013 - 1015 kg), suggesting that the stream is the product of steady disintegration of the parent at every return.
