PROBLEM TO BE SOLVED: To provide a compressor having a compact lubricating oil supply device capable of securing high reliability at low cost. SOLUTION: An oil pump 17 has a function to updraw lubricating oil 9. A pump case 41 storing the oil pump 17 is formed by drilling an end part wall 3a, and a recessed fitting part 42 is formed in a position decentered with respect to the axial center of the pump case 41 by predetermined amount. Trochoid tooth-shaped inner rotor 43 and outer rotor 44 are stored in the recessed fitting part 42, and a pump plate 45 is arranged so as to cover the rotors 43, 44. A flange 45b is formed around the front face of the pump plate 45, and a filter 46 formed on a ring corresponding to the inner diameter of the flange 45b is integrally provided. Due to the integration of the pump plate 45 and the filter 46, the filter 46 can be constituted by a small space and a small number of components, and thus, reduction of the size and weight of the sophisticated compressor can be achieved.
