There is provided an electric connection box in which even when a housing of a fuse is fusedly damaged by heat radiation or melting of a fusible element of the fuse, the fusedly-damaged housing can be restrained from adhering to an inner bottom portion of a fuse cavity. A conductive ink is applied to the lyophobic region and baked. The ratio of the cross-sectional area of each of the orifices to the cross-sectional area of the flow microchannels connected to the orifices is between 0.
