Abstract

Provided is a writing instrument or an applicator using resin parts formed, by way of two-color molding, to have an optimal guiding clearance between slide members. A plurality of resin molded parts is included. At least one of the plurality of resin molded parts is formed as a primary molding, and at least another one of the resin molded parts is formed as a secondary molding, by way of two-color molding, using a portion of a surface of the primary molding. The primary molding and the secondary molding are separated to be used as independent members. In this case, the primary molding and the secondary molding are preferably configured to slide against each other by each separating portion.
