Abstract: A heat spreader and an illumination device including the heat spreader are disclosed. The heat spreader includes a first substrate and multiple first heat dissipation fins, the multiple first heat dissipation fins are arranged side by side on the first substrate at intervals in a first preset direction, and the heat spreader meets constraints of the following Relational expression 1: N∈{L/[δ+9], L/[δ+9]+2} and Relational expression 2: H∈{[(δ1+δ2)/2−1.2]/tan 2θ, [(δ1+δ2)/2+1.2]/tan 2θ}. L represents a length of the first substrate in the first preset direction, represents a weighted average thickness of the multiple first heat dissipation fins, N represents a distribution number of the first heat dissipation fins, δ1 represents a maximum thickness of the first heat dissipation fin, δ2 represents a minimum thickness of the first heat dissipation fin, θ represents a draft angle of the first heat dissipation fin, and H represents a distribution height of the first heat dissipation fin.
