A scroll compressor comprising:

• a compressing mechanism unit including a fixed scroll fixed in a shell and an orbiting scroll configured to move around the fixed scroll, the compressing mechanism unit being configured to compress fluid;
• a main shaft including an eccentric shaft portion at one end and being configured to transmit a rotational driving force to the orbiting scroll;
• a slider having a slide groove in which the eccentric shaft portion is slidably fitted;
• and
• an orbital bearing provided to the orbiting scroll and rotatably supporting the slider;
• wherein
• the slider is provided only on an inner peripheral side of the orbital bearing when seen in a direction of a center axis of the slider,
• the center axis of the slider is eccentric in one direction from an axis of rotation of the main shaft,
• the slider includes a balance weight portion for adjusting a center of gravity of the slider,
• the center of gravity of the slider is eccentric in a direction opposite to the one direction from the axis of rotation of the main shaft, and
• the slider has a hollow portion that is separate from the slide groove.
