The invention provides a self-starting Raman enhanced substrate capsule combined with bubble enrichment, and belongs to the technical field of Raman testing. The capsule comprises an effervescent disintegrant and a Raman enhanced substrate, the capsule is automatically dissolved by placing the capsule in a to-be-detected solution system, the density of substances contained at the two ends of the capsule is different, the density of the Raman enhanced substrate part is low, and the density of the effervescent disintegrant part is high, so that after the capsule is placed in water, the capsule is automatically dissolved. When a substance to be detected is detected, the end of the Raman-enhanced substrate is naturally located above, bubbles generated by the effervescent disintegrant can directly act on the substrate, the Raman-enhanced substrate is spontaneously carried to a gas-liquid interface by rising power generated by the bubbles and stays at a stable interface, and a target detection object after bubble e
