The invention discloses an electronic detonator chip and an encapsulation method. According to the encapsulation method, by conducting dispensing curing hard encapsulation and low pressure injection molding encapsulation on a semi-finished electronic detonator chip, secondary encapsulation of the electronic detonator chip is achieved. In this way, under the premise that it is ensured that a product has the moisture-proof and dustproof functions, the production quality consistency of the electronic detonator chip is improved, the rate of finished products of the electronic detonator chip is increased, and seismic performance in the using process of the product is also improved greatly through double-layer encapsulation protection.
