PROBLEM TO BE SOLVED: To solve the problem that a connecting member made of a resin composition in which incorporated filler has a diameter smaller than a space (P-a) between adjacent fine holes can not keep the fine holes highly accurately, when the connection member is manufactured by filling a mold for forming with a resin composition and then solidifying the composition, wherein a plurality of fine holes of (aψ) or less are arranged while being in a row with a distance of a pitch P in one end surface, and holes for inserting guide pins are formed in both sides of the fine holes. SOLUTION: The connecting member is constituted of the resin composition in which the filler having a diameter including the maximum particle diameter larger than the space (P-a) between the fine holes filler is mixed. As a result, in the flow of the filler particles in the forming, the particles passed through the pin space and the particles not passed through the pin space are formed to improve the mechanical strength around the fine particle group and the excellent precision of the fine holes is attained.
