A wearable blood pressure detecting device is provided. The wearable blood pressure detecting device includes a case, a first pulse detecting module, a second pulse detecting module, and a blood pressure calculating unit. The case has a first detecting surface and a second detecting surface which is different from the first detecting surface. The first pulse detecting module is disposed on the first detecting surface for generating a first pulse signal. The second pulse detecting module is disposed on the second detecting surface for generating a second pulse signal. The blood pressure calculating unit is electrically connected to the first pulse detecting module and the second pulse detecting module for calculating the blood pressure value based on the first pulse signal and the second pulse signal.一穿戴式血壓量測裝置，包含一殼體、一第一脈搏偵測模組、一第二脈搏偵測模組與一計算單元。其中，殼體包含一第一偵測面與一第二偵測面。第一偵測面與第二偵測面位於殼體之不同面。第一脈搏偵測模組係設置於第一偵測面，以產生一第一脈搏信號。第二脈搏偵測模組係設置於第二偵測面，以產生一第二脈搏信號。計算單元係電性連接第一脈搏偵測模組與第二脈搏偵測模組，用以依據第一脈搏信號與第二脈搏信號以估算一血壓值。
