An electric switchboard according to the present disclosure includes: a power converter housed in a casing; an intake port and an exhaust port; a fan that causes air in the casing to flow from the intake port to the exhaust port; a first partition section dividing the inside of the casing into a first region where a low-heat-generation component is arranged and a second region where no low-heat-generation component is arranged; and a second partition section that is arranged downstream of the first partition section and divides the second region into an inner region where a high-heat-generation component is arranged and an outer area where no high-heat-generation component is arranged. The first partition section has a first inlet through which air in the casing flows into the first region, and a first outlet through which air that has flowed through the first region flows out to the second region. The second partition section has a second inlet that faces the first outlet while being spaced apart from the first outlet, and a second outlet through which air that has flowed through the inner region flows out to the outer region, the second partition section being formed so that the flow path cross-sectional area of the inner region gradually increases from the second inlet to the second outlet.
