PROBLEM TO BE SOLVED: To obtain a new thia/oxaporphyrin-based compound having optical or electric function. SOLUTION: The thiaporphyrin-based compound, the dithiaporphyrin-based compound, the oxaporphyrin-based compound, the dioxaporphyrin-based compound and the oxathiaporphyrin-based compound are represented by the general formula (R<SP>1</SP>-R<SP>8</SP>are each independently a hydrogen atom or an arbitrary substituent group; at least one pair of R<SP>1</SP>and R<SP>2</SP>, R<SP>3</SP>and R<SP>4</SP>, R<SP>5</SP>and R<SP>6</SP>and R<SP>7</SP>and R<SP>8</SP>is mutually bonded to form a ring which may contain a substituent group; X is S, O or NH; Y is S or O).
