PROBLEM TO BE SOLVED: To provide a rotation detection device which can be molded while maintaining signal transmission members in linear states under the molding pressure, and a manufacturing method of the same.SOLUTION: A rotation detection device 10 comprises a rotation detection part 17a, signal transmission members 11, an internal structure 15, and ribs 16a. The internal structure 15 is integrally molded with resin by including an attachment part 14 for attaching the rotation detection device 10 and a holding part 12 for holding the rotation detection device 10 at the attachment, and comprises a plurality of recessed parts 13b between the attachment part 14 and the holding part 12. In this structure, the plurality of recessed parts 13b are trails of holding the signal transmission members 11 during the integral molding. Thus, as the signal transmission members 11 and a housing part 17 are held, it is possible to perform integral molding by injecting resin while maintaining the signal transmission members 11 in linear states under the molding pressure. |
