A manufacturing method of a conductivity polymer organosilicon monomer is provided to manufacture a new organosilicon monomer at a condition that does not use a catalyst by introducing silicon atom with a superior reactivity. A thiophene derivative represented by chemical formulae 1 or 2 is manufactured by synthesizing a carboxylic acid derivative represented by chemical formulae 5 or 6 using a base represented by chemical formulae 3 or 4 in which a silicon atom is included and being decarboxylation-reacted under a decompression condition which does not use a catalyst. In the formulae, R is a methyl group, an iso-propyl group or a phenyl group.
