The purpose of the present disclosure is to provide an electrical device that ensures that at least the thermal conductivity between a heater and a heat sink reaches a predetermined degree, and that reduces the possibility of causing a decrease in the thermal conductivity. An electrical device (1) according to the present disclosure includes a heater (2), a heat sink (3), a thermally conductive sheet (4), and a thermally conductive fluid (5). The heater (2) has a first surface (20). The heat sink (3) has a second surface (30) facing the first surface (20). The thermally conductive sheet (4) and the thermally conductive fluid (5) are both interposed between the first surface (20) and the second surface (30). The first surface (20) and the second surface (30) face each other in their respective opposing regions. Each of the opposing regions includes a first region (21, 31) and a second region (22, 32) when viewed in a direction in which the first surface (20) and the second surface (30) face each other.
