The invention provides a miniaturized on-chip artificial surface plasmon even mode transmission line, the whole transmission line is composed of on-chip artificial surface plasmon periodic units which are connected in series, and each on-chip artificial surface plasmon periodic unit is composed of a microstrip line structure and folded open-circuit line branches which are symmetrically connected in parallel. Under the condition that the width of the transmission line is close to the width of an on-chip 50-ohm microstrip line, the field binding capacity far higher than that of a classic on-chip artificial surface plasmon even mode transmission line can be achieved, and low-crosstalk transmission between the two transmission lines can be effectively guaranteed. According to the invention, the field constraint characteristic of a lower frequency band can be enhanced by increasing the unit length of the transmission line, and the field constraint capability can be further improved under the condition that the wid
