The given polynomial equation is:

\[
3x^5 - 2x + 1 = 0
\]

### Step-by-step analysis:

1. **Degree of the polynomial**: The highest power of \( x \) in this equation is 5, meaning that this is a 5th-degree polynomial.

2. **Fundamental Theorem of Algebra**: This theorem states that a polynomial of degree \( n \) has exactly \( n \) roots (real or complex). Therefore, this polynomial has 5 roots in total.

3. **Nature of roots**: Since the coefficients of the polynomial are real, any non-real roots must occur in conjugate pairs. The exact number of real versus complex roots depends on the behavior of the polynomial, but we know that all the roots combined must equal 5.

4. **Real and complex roots**: Since not all the roots of this polynomial are guaranteed to be real, there must be complex roots. The number of real roots will depend on solving the equation, but based on the degree, we know that any remaining roots will be complex.

### Conclusion:
Since the polynomial is of degree 5, the total number of roots is 5. At least one of these roots could be real, but the rest must be complex. Therefore, **the polynomial must have 3 or 5 complex roots**. Given that some real roots are likely, the number of complex roots is **3**.

### Final Answer:
The number of complex roots is 3.
