Abstract
There is provided a new and improved reel member and a new and improved reel housing body that can suppress surface runout and accordingly suppress falling-off of an adhesive film, the reel member (1) including: a winding core section (2) around which an adhesive film is windable; and a flange section (3) provided on each of both end portions in a direction of a rotation axis of the winding core section, in which the winding core section and the flange section are provided separately from each other, and an amount of surface runout of the flange section is a value within a range of ±0.2 mm. For example, a diameter of the winding core section and a diameter of the flange section may satisfy a predetermined mathematical formula.
