This component supply device (1) supplies components (P) stored in a component storage tape (100) to a component removal position (21). This component supply device (1) is provided with a component exposing unit (6) which exposes a component (P) in the component storage tape (100), which is conveyed by a tape conveying unit (3) so as to travel along a travel path (5) formed from a tape travel pathforming unit (4). The component exposing unit (6) includes a cover tape raising section (61) that performs processing for raising the cover tape 102. Also, on the travel path (5) formed by the tape travel path forming unit (4), a first route section (51) on which the cover tape raising section (61) is arranged is configured so as to incline in one direction in the Z-axis direction from upstream towards downstream in the tape conveyance direction (H).
