Abstract
An optical fiber fixing member having optical fiber engagement grooves,and peaks,between the engagement grooves,is configured as a unitary structure by molding. A preform G is pressed with a mold,such that the concavities,of the mold,, which comprises convexities,and concavities,for the transfer of the engagement grooves,and the peaks,, respectively, are filled with the preform G only partially. The shape of the convexities,of the mold,is transferred, yielding optical fiber engagement grooves,whose surfaces are mold transfer surfaces,. Because the preform G fills the concavities,only partially, the peaks,between the optical fiber engagement grooves formed by the filling of the concavities,are free rounded surfaces,whose shape does not reflect the shape of the concave bottom portions,of the mold
