Abstract
An electric connection box includes an electronic circuit board having an electronic component, and a power circuit board having a power circuit, which are disposed upright in a casing. A vertically-extending component area for mounting a heat generating component is formed on the power circuit board, so as not to face the electronic circuit board. A partition wall for separating the component area from the electronic circuit board is provided in the casing, and thereby a first air passage for allowing air to flow vertically along the component area is formed in the casing. A first inlet port connected to the first air passage is formed on the casing, and a first outlet port connected to the first air passage and positioned above the first inlet port is formed on the casing.
