  "textContent": "The present invention provides a supercharger with an electric motor having improved cooling performance for bearings, in the case of employing a grease lubrication system as a lubrication system of the bearings. A supercharger with an electric motor (1a, 1b) includes: a rotary shaft (12); a compressor wheel (10); a compressor housing (2) for housing the compressor wheel; an electric motor (15) including a motor rotor (14) and a motor stator (16), and giving rotation force to the rotary shaft; a motor housing (6a, 6b) for housing the electric motor; a first grease-sealed bearing (20A) for rotatably supporting the rotary shaft; and a bearing housing (4a, 4b) for housing the first grease-sealed bearing, and disposed between the compressor housing and the motor housing. Inside the bearing housing, a cooling passage (18a, 18b) through which a cooling medium flows is provided in a circumferential direction on an outer circumferential side of the first grease-sealed bearing.",
