A kind of physiological function detection band, including ontology, sensing mould group, band body and accommodating bag. It senses in mould group installing what ontology, and connect the sensing unit and the power supply unit of the display element including sensing unit, display element and electrical property. The side of sense unit appears the Hou side of what ontology, to contact human skin, and measures heartbeat. Band body connects what ontology, ontology is fixed what human body. Accommodating bag sets the leading flank of what ontology, including an at least inner layer piece, an outer-skin sheet and one of forms sack by the outer-skin sheet and the inner layer piece are stacked, in can accommodate an action electronic device.一種生理機能偵測帶，包括本體、感測模組、帶體及容置袋。感測模組裝設於本體內，並包括感測單元、顯示元件、及電性連該感測單元及該顯示元件之供電單元。感單元之一側顯露於本體之後側面，用以接觸人體皮膚，並量測心跳。帶體連接於本體，用以將本體固定於人體。容置袋設於本體之前側面，包括至少一內層片、一外層片及由該外層片和該內層片疊置形成之一袋口，其內可容置一行動電子裝置。
