A scroll compressor according to the present invention includes a partition plate that partitions a sealed container into a high-pressure space and a low-pressure space, a fixed scroll adjacent to the partition plate, a orbiting scroll, a rotation restrictor, and a main bearing. The sealed scroll compressor further includes a pillar member having a lower end portion secured in a bearing-side engagement portion provided in the main bearing, and an upper end portion inserted in a scroll-side engagement portion provided in the fixed scroll. The axial distance from the upper end portion of the pillar member to the partition plate is smaller than the length by which the pillar member and the bearing-side engagement portion are coupled together.
