Abstract: A toy brick includes a plastic main body, and a soft and elastic subsidiary part different color from the main body; the main body has a middle connecting through channel, first holding trenches on a front side thereof, and second holding trenches formed on surfaces of comers located between every adjacent two of upper, lower, left, and rear sides thereof; the subsidiary part has a middle sleeve portion closely fitted in the connecting channel of the main body, first covering portions adhered to corresponding ones of the first holding trenches of the main body, and second covering portions adhered to corresponding ones of the second holding trenches; thus, toy bricks of the kind will produce less noise when hitting each other or the floor, and are less hard at the corners.
