摘要：
An encoder (100) comprises a first substrate (125) comprising a point light source (121) that emits light onto reflective slits formed on a disc (110) and a light-receiving element (122a, 123a) that receives light emitted from the point light source (121) and reflected by the reflective slits, a second substrate (130) onto which the first substrate (125) is mounted, a lustrous connecting portion (180) configured to electrically connect the first substrate (125) and the second substrate (130), and a covering material (190) configured to cover the connecting portion (180) in the manner that the point light source (121) and the light-receiving element (122a, 123a) are exposed.
